I’ve put my hair through the ringer over the years, all because I was desperate for smooth hair. Instead of treating the cause of any dryness or added damage, I instead subjected my long strands to an excessive amount of Japanese hair strengthening, keratin, Brazilian blowouts, and flat irons with extreme high heat (it’s too embarrassing to ever admit what temp I used, but use your imagination). Since, I’ve course-corrected, and have become quite meticulous when it comes to hair products I use. So when amino acid hair treatments started flooding the market, I took special interest.

Vogue’s Favorite Amino Acid Hair Treatments:

As Charlene Valledor, cosmetic chemist and co-founder of SOS Beauty explains, amino acid hair treatments are typically designed to strengthen and smooth hair by filling in the gaps in the cuticle and provide protection from moisture loss. It’s much gentler than known formaldehyde-based straightening treatments like the keratin treatment, and she says it’s a great option for anyone looking to minimize damage while keeping their natural texture.

So if you’re looking for restorative options that will keep your hair integrity intact, amino acid hair treatments might be exactly what you need. Below, everything you need to know; plus, the five best ones you can try.
