I recommend a shampoo that softens hair damaged by dyeing.

Basically, this product cares for hair and roots damaged by dyeing, perming, and the hot summer sun. I really love it because just shampooing makes my hair instantly soft, just like I used a conditioner. True to its name, it is an extreme damage care shampoo, so it was more effective than regular shampoos for damaged hair. Although the ingredients are herbal, it has absolutely no herbal scent, so it is pleasant and not at all overpowering. While conditioner is important, using a shampoo specifically designed for severely damaged hair is even better.
