Reddit mentions of Deesse's Linkage Meu 4x Treatment 0.3oz.

I had really dry hair when I bleached it a few times. I know it's not the same situation as you but maybe it can be helpful. I first used this treatment my friend got from Japan: https://www.amazon.com/gp/product/B005DQUVS2/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 . I use it about once a month. Then I found that the Briogeo Don't Despair, Repair! deep conditioner helped a lot. I basically used it every time I washed my hair. It's a little expensive but you don't need to use a whole lot. Then I would use those fancy no frizz towel wraps while I finished showering. After that I apply argon oil and leave in conditioner to my wet hair and wrap a clean t shirt around my head. I let my hair absorb all the goodness for as long as I can stand it, which is 20 mins. I just let it air dry after that or blow dry on low. I try to wash my hair every 3 or 4 days. I can hold out a little longer in the winter time. After about a month my hair started to look normal again. After a few months my hair is actually pretty soft and barely even frizzy. Hope this helps and good luck to you!
