A Dermatologist Says This $17 Hair Serum ‘Boosts Thickness’ — and It All Comes Down to One Ingredient

Staying consistent with your hair care routine is no easy feat. It can take a ton of effort and time in your daily routine, not to mention it can sometimes take months to even finally see noticeable results.  That’s why I like to stick to hair growth serums to stay on track with maintaining a healthy head of hair. They’re incredibly easy to use (taking literal seconds) and allows you to directly target thinning areas like a receding hairline or widening part. When it comes to finding the right product that won’t go over budget, a dermatologist told me to try this $17 mane-thickening product: the Bare Anatomy Advanced Hair Growth Serum.

Bare Anatomy Advanced Hair Growth Serum 

This lightweight hair serum is packed with natural ingredients like redensyl, anagain, and capilia longa formulated to increase hair’s density. This powerful blend works to reduce hair fall and stimulate new growth by extending the anagen (growth) phase of the hair cycle. Board-Certified Dermatologist Dr. Kristina Collins explained to Shape that capilia longa concentration of peptides are another essential component for growth, saying that they’re one of the “most studied and effective ingredients for boosting thickness and reducing hair loss.” 

The non-greasy formula also contains a blend of hair-strengthening ingredients like rosemary, biotin, and rice water that improves breakage and create more manageable strands. A 2015 study even found that rosemary oil offers similar results to minoxidil, an FDA-approved ingredient) for tackling hair loss. It is also known to block the hormone DHT (dihydrotestosterone) that contributes to hair thinning. 

And rosemary’s revitalizing benefits don’t just end there — the extract’s anti-inflammatory and antimicrobial properties help soothe a dry, itchy scalp including conditions like dandruff. Meanwhile, its potent antioxidant properties are another bonus for hair’s health. Dr. Collins explained it can “improve follicle longevity and scalp health” as they protect against environmental aggressors.

Reviewers claimed this hair growth oil improved hair’s appearance only after a few months of consistent use. “[My hair] feels much healthier and I barely lose any hair anymore,” said a shopper who added that their mane looks “so much thicker” after a month. A second shopper similarly raved that they saw “tremendous growth” in bald areas in the same time period, while another user noticed “a difference in the density and quality of my hair” after three months.
