First issues first: Collagen doesn’t make up hair.
Collagen is a protein discovered within the pores and skin, intestine, joints, and all through the physique to offer construction and power. Hair, however, is predominantly made up of one other protein, keratin. (Keratin can be present in your dermis and nails.) Keratin is a protecting protein that acts as a barrier. All proteins are made up of amino acids, typically known as “the constructing blocks” of proteins.
So why is collagen typically marketed towards hair well being? Effectively dietary supplements like collagen powder aren’t really the complete collagen molecule (which might be too massive to digest), however reasonably damaged down and hydrolyzed collagen. On this kind, it’s really absorbable amino acids!
Basically: The amino acids in collagen dietary supplements can be utilized by the physique to supply different proteins, similar to keratin.
Licensed trichologist and founding father of Superior Trichology William Gaunitz, FWTS, informed mbg that the first amino acid that’s most useful is named proline1. Many collagen dietary supplements are clear in regards to the amino acid profile inside their system, so you’ll be able to even discover choices that comprise this amino acid and are possible higher fitted to hair well being.
However it’s not simply in regards to the hair fiber itself, collagen can really assist the hair follicle and surrounding space. Rachel Maiman, M.D., board-certified dermatologist at Marmur Medical, notes that analysis has proven that collagen ranges in surrounding the hair follicle and bulb improve throughout hair development part2 (in any other case known as the anagen part).* Then once they go into the upkeep and shedding part, the collagen disappears.
So if the physique can create extra collagen, it could possibly assist hair within the development part for longer. “As our our bodies create extra collagen, the layers regenerate. This helps our hair follicles by helping them in re-entering the anagen part and sustaining the hair development cycle,” says Maiman.*
Certainly, we regularly discuss how one can’t have wholesome hair and not using a wholesome scalp. “Collagen helps the scalp’s thickness,”* Maiman says. “A skinny scalp with inadequate collagen is much less sturdy and fewer able to holding the hair follicle bulbs in place.”
