Best product for breakage & over processed hair [SEP] This stuff is a miracle! If you’ve over processed your hair this will save it from breakage. I bleach my own hair and I more than 1 occasion I’ve overdone it & had my hair start snapping off & this stopped it immediately! But be careful & don’t use it too often, too much protein is bad too & can cause damage. Best product has saved me in several instances. I keep this on hand ALWAYS!
