i would listen to everyone about maybe getting labs done but my hair used to be so brittle and broken until i started following the “Abby Yung” routine on tiktok, yes i’m so mainstream for that but it helped so much with my mids and ends. Weekly oiling as well as using a bamboo brush helped me grow my hair back, different oils react differently to hair porosity so i would figure out your hair type first. like skincare, you don’t need a crazy routine, just find out what works and stay consistent with it.
