For people concerned about the environment, we suggest Foamie, an ecologically conscious German brand that wants to revolutionize the bathing experience with 100% vegan soap-free solid shampoos, with a three-in-one action: massage, clean and nourish. It is available in several fragrances that should be used depending on your hair type. The one with aloe vera and almond oil is for dry hair; that of hibiscus and nettle extract for the damaged; coconut oil and wheat protein for normal hair; and berry extract for fine hair.
