I used Sea Breeze astringent and Mane โn Tail horse shampoo for a month โ did the trick! Also invested in a humidifier and kept it running by my bedside at night. Satin or silk pillowcases also help.
Use something like olaplex no 6 put it in your hair and leave it for like 16 hours as a mask. Look for a rosemary oil (mielle organics one is good) and a scalp serum like maybe the one from Vegamour or act+acre
Sorry this is kind of vague rn but I can get more specific if you want
Just every once in a while, specially if you like to not wash your hair everyday or if you use a lot of things to style it. make sure to pair it with a moisturizer on your ends hehe :)
