To be honest, I haven't dyed my hair very much, but my hair was already beginning to feel dry with tons of split ends. However, TRESemme helped give me my hair back. Although the shampoo was not what I would prefer to spend on a shampoo, TRESemme often sends coupons. In just a short amount of time, my hair was already beginning to feel smooth and silky again. My hair no longer felt coarse or looked bad when it became oily. My split ends are no longer there, and I would recommend this to anyone who dyes their hair every once in a while. I don't think this shampoo would have the same effects if used regularly or if you dye your hair on a daily basis. However, TRESemme does an amazing job taking care of your hair even with the dye and makes your hair feel great and natural. Effectiveness Perfect to help your hair that's been colored or damaged in any way. Scent Pretty good scent that stays in your hair for days due to the texture of the shampoo.
