Many find that it dries quickly, allowing them to style their hair without waiting around, which is a big plus for busy routines.
Although most users are satisfied with the absorption, a small group reports that they sometimes feel a slight residue on their scalp after application. A few reviewers also mentioned that it can leave their hair feeling slightly oily if not applied sparingly, particularly for those with finer hair.
Non-Greasy Formula

The serum’s lightweight, non-greasy formula is a major selling point. Many users mention that it doesn’t weigh their hair down or make it appear oily, even with regular use. The smooth application and quick absorption make it a top choice for people who want an effective product without compromising on style or comfort.
Some individuals with extremely dry scalp conditions reported that the serum, while not greasy, doesn't provide enough moisture. For these users, it may feel a little too light, especially in colder climates or during harsh winter months.

Many mention that their hair feels fuller, and some say they’ve noticed less shedding after consistent application. This product works well for those who prefer a long-term solution rather than a quick fix.
Despite the positive feedback, some users were disappointed with the slower pace of results. It may take longer than anticipated for noticeable changes to occur, which can be discouraging for those looking for quicker outcomes, especially when comparing it to other products that promise faster regrowth.
Value for Money
89%
At its price point, many users believe this serum offers great value for money. The large 4.66oz bottle is often highlighted as an economical option compared to smaller, more expensive serums that provide similar results. Those who follow the recommended twice-daily usage find the product lasts for a long time, making it a solid investment for hair care.
While the overall value is praised, a few users feel that the price is a bit high considering the slower pace of visible results. Some also mentioned that if they didn’t see faster regrowth, they would prefer a less expensive alternative, making the cost a concern for those on a budget.

The combination of ingredients works synergistically to improve follicle health over time.

The serum is especially beneficial for those experiencing mild to moderate thinning, helping to add volume and improve texture. Many users have reported feeling more confident with thicker, fuller hair after continued use.
