Peptides have become increasingly popular in hair care, particularly in scalp serums formulated to support healthier-looking, fuller hair. These short chains of amino acids are being investigated for their potential role in supporting hair follicle activity and improving hair thickness.
Research has explored the potential of specific peptides in supporting hair growth. A 2016 study involving 22 Japanese men with androgenetic alopecia found that topical Gly-Pro-Ile-Gly-Ser (GPIGS) increased the proportion of thick hair over four months. However, this specific peptide, also known as Pentapeptide-20, does not appear in the ingredient list of the Saturday Skin Scalp + Hair Strengthening Peptide Serum. Therefore, the study's findings cannot be directly applied to this product. Read the study on PubMed.
Still, with this in mind, I was curious to see how the Saturday Skin Scalp + Hair Strengthening Peptide Serum would perform. It's been a while since I last tried products from Saturday Skin, including the Waterfall Glacier Water Cream, Daily Dew Hydrating Essence Mist and Spotlight Brightening Mask.
