A lot of my hair died on the top and presumably around the cowlick area too after using tresemme too . Wound up with a bunch of dead hairs and looked nothing more than like a chaoic hair-wise ragdoll and i had to break all the dead-hair chaos off of it - i mean u can literally pick whatever tresemme shampoo and conditioner or product u want it doesnt matter what tresemme product u use it'll just mess up your hair theyre a bunch of asses (sorry for freaking out and for any language i'm using) . I had do more cutting and trimming and more vitamin intake all the good stuff u name it (and even hair growth music therapy also) until something happened and some spots where i'd previously messed it up they actually started to grow back in spots where i'd not seen any hair . It's getting fuller on the top now too
