Do Hair Peptide Serums Really Work for Female Hair Loss?

Female hair loss, especially during midlife, is a big issue for a lot of women. Finding clumps of hair in your comb can be truly discouraging, leaving you to think, “Why is this happening to me?” while it seems like everyone else has full, beautiful locks.

Just so you know, about half of women over 50 deal with some level of hair thinning. Menopause plays a big role in this, as it brings hormonal changes, particularly a drop in estrogen, which can lead to finer hair and slower growth. Genetics can also be a factor, along with emotional stress or physical challenges.

But don’t let these changes get you down—Hair Peptide serums can actually help your hair become thicker.

What are hair peptide serums?

Hair peptide serums contain peptides, amino acids, and other ingredients that nourish and strengthen hair. Known for their ability to stimulate the production of collagen, an essential protein that gives hair strength and elasticity, they are applied directly to the hair and scalp and may stimulate hair growth, reduce hair breakage and damage, and promote overall hair health.

“Peptides encourage hair growth by improving blood flow to the scalp and strengthening the structure of hair follicles,” shares Dr. Candace Thornton Spann, a board-certified dermatologist in Las Vegas and the co-owner of Couture Dermatology & Plastic Surgery. “They can also result in the formulation of more collagen, a building block that’s vital to the health of the hair follicle,” she adds.

Are hair peptide serums effective?

In 2024, several peptide serums for hair growth have received high praise from dermatologists and beauty experts suggesting a growing consensus in the scientific community regarding the efficacy of peptide serums in managing hair loss.

A survey of dermatologists also indicated a strong preference for peptide formulations in treating conditions like telogen effluvium (TE) and androgenetic alopecia (AGA), with many reporting good adherence to these treatments among patients.

Our verdict

Typically, it takes about 1 to 3 months to see noticeable results from using peptide serums for hair growth. However, the exact timeline can vary based on individual factors such as skin type, the specific product used, and the frequency of application.

Overall, patience and consistency are key when using peptide serums. If noticeable hair loss is upsetting you, schedule a visit to a dermatologist, who can examine your scalp and order blood work to check for possible underlying causes for the hair loss.
