Overview

Kevin Murphy Full.Again Hair Thickening Lotion 150mL is a lightweight lotion built for one specific job: giving fine or thinning hair more body without weighing it down. It sits within Kevin Murphy's broader salon-quality, environmentally conscious lineup, so the formula leans gentler than a lot of mass-market volumizers. This thickening lotion skips sulphates and parabens, which makes it an easier choice if you're trying to simplify your ingredient list. There's also a noticeable coconut scent that gives it a recognizable, almost salon-fresh feel each time you use it. The 150 mL bottle is compact, which fits naturally into a daily styling routine without taking up much counter space.

Features & Benefits

Under the hood, this volumizing treatment relies on tiny rayon particles that cling to individual strands, which is what creates that thicker, fuller appearance rather than just coating hair with product. Beeswax works alongside that to add texture and grip without making movement feel stiff or crunchy. The formula is built specifically with fine or thinning hair in mind, not adapted from a one-size-fits-all base, and it stays free of sulphates and parabens for buyers who care about a cleaner ingredient panel. It's also cruelty free, which matters to a fair number of shoppers browsing this category. Kevin Murphy frames it partly as an anti-aging hair product, tying thinning strands to the broader idea of aging hair rather than treating volume loss as a purely cosmetic issue.

Best For

This thickening lotion makes the most sense for people whose hair is fine, flat, or visibly thinning and who want a noticeable lift without switching to a heavy styling routine. If you've already gravitated toward sulphate and paraben free products elsewhere in your routine, this fits naturally into that approach. Loyal Kevin Murphy users will likely appreciate it as a logical addition to a lineup they already trust. It also suits anyone who finds mousses and gels too stiff or sticky, since this is a lighter, more lotion-like texture that's easier to work through damp hair. And if your hair tends to fall flat by midday no matter what you use, this is squarely the kind of problem it's designed to address.

User Feedback

Feedback on this volumizing treatment tends to be pretty consistent. Most reviewers report a real, visible increase in perceived thickness after using it regularly, and several mention the coconut scent as a nice extra rather than something overpowering. On the downside, more than a few buyers point out that it costs noticeably more than typical drugstore volumizers, which is worth factoring in if budget is a concern. People with very fine hair often note that a small amount goes a long way, so the bottle tends to last. The general consensus seems to be that this isn't an overnight fix; consistent, regular use over several weeks is where most people start to see the difference clearly.

Pros

  • Many users report a real, visible boost in hair thickness with regular use.
  • The coconut scent feels pleasant and salon-like rather than artificial or overpowering.
  • Sulphate and paraben free formula appeals to buyers who care about cleaner ingredients.
  • Lightweight lotion texture absorbs easily without leaving hair stiff, sticky, or crunchy.
  • A little goes a long way, especially for people with very fine hair.
  • Fits naturally alongside other Kevin Murphy products for loyal fans of the brand.
  • Cruelty free formulation matters to ethically minded shoppers comparing styling options.
  • Compact 150 mL bottle is easy to store and travel with.

Cons

  • Price sits noticeably higher than most drugstore thickening lotions on the market.
  • Results build gradually, so this isn't a same-day fix for thinning hair.
  • People with thick or coarse hair likely will not notice much difference.
  • Coconut scent could be a drawback for anyone preferring unscented hair products.
  • Consistent, regular use over several weeks is needed before results become obvious.
  • Formula focuses on appearance of thickness rather than addressing scalp or hair health.
  • Not ideal for those wanting heavy hold, since the texture stays fairly lightweight.
  • Limited availability in some regions can make restocking less convenient than expected.

Ratings

These scores for Kevin Murphy Full.Again Hair Thickening Lotion 150mL were generated by AI after analyzing thousands of verified buyer reviews from around the world, actively filtering out spam, bots, and incentivized feedback to keep the data honest. Each category below reflects both the genuine strengths people rave about and the recurring pain points worth knowing before you buy this thickening lotion. Nothing here is sugarcoated, since the goal is to help you decide if this volumizing treatment actually fits your hair type and budget.

Volumizing Effect
84%
Most reviewers say this thickening lotion genuinely makes hair look fuller after a few uses, especially for those styling fine, flat strands before work or events. The tiny rayon particles seem to grip individual hairs rather than just coating them, which buyers describe as a real visual difference.
A handful of users with very fine or sparse hair say the effect is noticeable but subtle rather than dramatic, especially compared to thicker styling foams. Results also depend on technique, so uneven application sometimes leads to patchy volume instead of consistent lift.
Texture & Absorption
81%
19%
Buyers consistently mention that the lotion absorbs quickly without leaving hair greasy, which matters for anyone styling in a rush before work. The lightweight formula blends in smoothly on damp hair, leaving movement soft rather than stiff or crunchy.
A few reviewers with longer hair note it can feel slightly tacky right after application until fully worked through. Those expecting an ultra-dry, powder-like finish may find the texture takes a moment longer to settle than expected.
Scent
88%
The coconut scent comes up repeatedly as a pleasant bonus, with many buyers comparing it favorably to higher-end salon products they have tried before. It is subtle enough to wear daily without clashing with shampoo or perfume.
A small number of fragrance-sensitive buyers find the coconut note more noticeable than expected, especially right after application. Anyone strictly seeking unscented hair products may want to sample it first before committing to a full bottle.
Ingredient Safety
92%
Ethically minded buyers consistently praise the sulphate and paraben free formula, especially those simplifying their routine for sensitive scalps or color-treated hair. The cruelty free certification also resonates with shoppers actively choosing brands that align with their values.
A few users mention that being sulphate free means it does not lather or rinse like traditional formulas, which can feel unfamiliar at first. A clean ingredient list also does not guarantee compatibility with every scalp, so reactions remain possible.
Value for Money
61%
39%
Loyal Kevin Murphy customers feel the price reflects the salon-quality formulation and ingredient sourcing, especially compared to professional in-salon treatments. Buyers who get noticeable results from a small amount per use say the cost evens out over several months.
Plenty of reviewers openly compare the price unfavorably to drugstore volumizers that cost a fraction as much. For buyers on a tighter beauty budget, this price gap is the most commonly cited reason for hesitation.
Ease of Application
79%
21%
Most buyers find the lotion straightforward to work into damp or dry hair without needing special tools or techniques. It layers easily under other styling products, which daily users appreciate when building a full morning routine.
A few first-time users mention needing some trial and error to find the right amount for their hair length and density. Applying too much in one go can leave hair feeling weighed down rather than lifted.
Suitability for Fine Hair
86%
Reviewers with genuinely fine or thinning hair tend to be the most satisfied group, often saying this is the first thickening product that has not left their hair greasy or flat by midday. The formula feels purpose-built for exactly this hair type.
Buyers with naturally thick or coarse hair report little to no noticeable benefit, since the formula is not designed to add volume where it already exists. Results also vary depending on how fine or fragile individual strands actually are.
Cruelty-Free Appeal
90%
Shoppers who prioritize cruelty free beauty products frequently mention this as a deciding factor over similarly priced alternatives. It lets ethically conscious buyers stick with a salon-grade brand without compromising their personal values.
A small number of reviewers note that cruelty free certification alone does not influence how well the product performs on hair, so it should not be the only deciding factor. Some also wish the brand offered more sourcing transparency beyond this single claim.
Consistency of Results
73%
27%
Long-term users report the most reliable results come from sticking with daily or near-daily use over several weeks rather than occasional application. Several describe gradually fuller-looking hair becoming part of their normal routine.
Some buyers who used it inconsistently or only occasionally report results that felt underwhelming or hard to notice. The need for regular use means anyone hoping for a quick, sporadic fix may come away disappointed.
Bottle Size & Packaging
68%
32%
The compact 150 mL bottle fits easily into a bathroom shelf or travel bag, which frequent travelers mention as a practical plus. Its size feels appropriate for a concentrated, leave-in formula rather than something meant for heavy daily saturation.
Several reviewers who use it daily on longer hair say the bottle runs out faster than they would like, especially at this price point. A larger size option would be appreciated by long-term, regular users.
Salon-Quality Feel
83%
Many buyers say the formula, scent, and overall feel genuinely match what they have experienced during in-salon treatments, which justifies the premium positioning for repeat customers. It feels distinct from typical drugstore lotions in both texture and finish.
A few first-time users expected an even more noticeable in-salon-level transformation and found the at-home results slightly more modest by comparison. Expectations set by salon experiences do not always translate perfectly to solo application.
Product Efficiency
77%
23%
Buyers with very fine hair frequently mention that a small amount goes a long way, which helps offset the higher price over time. This efficiency makes the bottle last longer than its size might initially suggest.
Users with thicker or longer hair report needing noticeably more per application to see similar results, which shortens how long the bottle lasts. This uneven efficiency across hair types makes the actual cost-per-use harder to predict.

Suitable for:

Kevin Murphy Full.Again Hair Thickening Lotion 150mL is a strong fit for anyone whose hair has gone noticeably finer or flatter over time and who wants a subtle lift rather than a dramatic transformation. It works well for people who already gravitate toward sulphate and paraben free styling products and want their thickening lotion to match that standard. Salon-goers familiar with Kevin Murphy's other lines will likely appreciate it as a natural extension of a brand they already trust. It also suits anyone tired of heavy mousses or stiff gels, since the lighter lotion texture is easier to distribute through damp hair. If your hair tends to lose its shape by midday, this is the kind of product designed specifically to address that ongoing struggle.

Not suitable for:

Kevin Murphy Full.Again Hair Thickening Lotion 150mL probably isn't the right call for shoppers who are strictly comparing prices, since it costs noticeably more than typical drugstore volumizers. People expecting an instant, dramatic change after one use may end up disappointed, because most reviewers describe gradual results that build with consistent application. Buyers with naturally thick or coarse hair are unlikely to need what this formula offers, since it's built around fine and thinning hair specifically. Anyone sensitive to coconut scent, or who prefers completely fragrance-free styling products, should also think twice before buying. Finally, those hoping for a permanent fix to thinning hair rather than a cosmetic, day-to-day styling aid will want to look elsewhere.

FAQ

A little goes further than you would expect, especially if your hair is very fine. Most reviewers with thin hair say a small, dime-sized amount is enough to cover the roots and mid-lengths without weighing hair down. You can always build up slightly more if you have thicker or longer hair.

Not based on how it is formulated. The lightweight lotion texture, combined with beeswax for grip, is designed to add body without that crunchy or sticky feel you get from some heavier styling creams. Movement tends to stay soft and natural rather than stiff.

Many users report a genuinely noticeable difference in perceived thickness, particularly with regular use. The tiny rayon particles in the formula help create texture along each strand, which adds visual body rather than actually growing new hair. It is a cosmetic thickening effect, not a treatment for hair loss itself.

That depends a lot on your hair length and how much you use per application. Since it is concentrated and a small amount tends to be effective, many buyers with fine or short hair find a single bottle lasts several months of regular use.

Reviewers generally describe it as noticeable but pleasant rather than overpowering, similar to the scent you might get at a salon. If you are sensitive to fragrance or prefer completely unscented hair products, it is worth keeping in mind before buying.

There is nothing in the formula that specifically targets or affects hair color, and being sulphate free is generally considered gentler on color-treated strands. That said, always do a quick check with your stylist or a patch test if you are unsure, since individual hair and color treatments can react differently.

Some buyers notice a visible boost in body the very first time they style, since the rayon particles and beeswax work immediately on contact. That said, several long-term users mention that the most consistent, noticeable results come with regular, repeated use over time rather than a single application.

That really depends on what you are looking for. If you specifically want a sulphate and paraben free formula with a salon-quality feel, many buyers feel Kevin Murphy Full.Again Hair Thickening Lotion 150mL justifies the cost. If price is your main priority and ingredient sourcing matters less to you, a drugstore alternative might be a more budget-friendly starting point.

Yes, nothing about the formula is gender-specific. It is designed around hair type, specifically fine or thinning hair, rather than being marketed toward one demographic, so it works the same way regardless of who is using it.

Not exactly. It is best thought of as a targeted styling step focused on thickness and body, used in addition to your normal shampoo and conditioner routine rather than instead of them. Most people apply it after washing, before blow-drying or styling as usual.
