If you want to achieve longer, thicker hair, then this hair growth serum is worth trying out.

Looking to get longer, healthier hair? Then you'll most likely be considering adding a growth serum into your haircare routine.

If you don't want to browse all the bottles on the market, then one said to "work like magic" is the Bare Anatomy Advanced Hair Growth Serum (30ml) that can be bought for just £17.99 on Amazon.

To help stimulate new hair growth, the serum uses a clinical blend of hair growth actives such as Redensyl, Anagain, Baicapil and Capilia Longa. This "unique" formula is said to extend your hair's anagen phase (the growing phase.)

It also combines three powerful hair growth ingredients such as biotin, rosemary oil and rice water, all which work together to strengthen weak hair, prevent breakage and reduce dryness.

Designed to be "lightweight" and "non greasy" on your hair, this particular serum is said to be ideal for anyone who struggles with and wants to target thinning hair, hair breakage, bald patches and a wide middle parting.

According to the Bare Anatomy brand, its hair growth serum has led to an 89 percent in hair loss reduction, while hair growth is said to increase by 214 percent in just 10 days. Meanwhile, 97 percent of users are said to have noticed an increase in their hair density in as little as 45 days.

And it's said to live up to its promises, as the Bare Anatomy Advanced Hair Growth Serum has earned an impressive 4.2 rating based on 1,945 Amazon reviews that say it is "the best" on the market and provides a "noticeable difference" in hair growth and health.

One beauty fan praised: "This is indeed the best hair growth serum I've used so far. Works like magic. My hair fall has surely reduced. It is non greasy. It's an affordable serum as compared with others. True value for money product. Definitely go for it! Thank you for such an amazing product."

A second agreed: "Best hair growth serum truly works. This serum is a game-changer! It absorbs quickly, strengthens roots, and reduces hair fall. With consistent use, I’ve noticed visible hair growth and thicker, healthier strands. Lightweight, non-greasy, and super effective highly recommended!"

Another delighted shopper said: "Generally I don't write reviews but this serum worked like miracle for me. I saw new hairs growing out after one week of daily usage. It's been a month now and I'm very happy with the results. You just have to be consistent with it. Overall it's worth it."

Someone else added: "This hair growth serum has made a noticeable difference for me! It’s helped reduce hair fall and promote growth, leaving my hair feeling thicker and healthier. The blend of natural ingredients like Rosemary and Biotin has really worked wonders for my hair health."

Not everyone was overly impressed with the results, as one three-star review read: "The product is good but there is no need of the hype which has been created because I am using from two months but haven't seen much change."
