For Fine/Limp Hair

For Curly/Dry Hair
Start with a gentle curl cleanser like a low- or no-poo, then follow with a moisturizing pick. Make sure you’re lathering up as little as possible.

In a word, your hair is thirsty. Nourish it with moisturizing ingredients like prickly pear oil and tamarind seed extract—and then lay off the heat for a minute.
