I use Herbal Essence Daily Detox Clean shampoo it’s £1.95 here so bout $2 the whole family using for the last 4-5 years. It’s not specifically for Afro hair but all hair is protein I’m not prepared to pay over the odds for specific shampoos for “black” hair they are literally over priced & not necessarily any better than regular ones made for Caucasian hair. So I don’t know if you have it in the States but there are 2 fragrances & they both smell Devine & get hair really clean. Failing that Tresemmé Replenish & cleanse shampoo is also not bad 👍🏾🇬🇧
