My 5 year old daughter has severe contact dermatitis so I have to be careful with anything that comes in contact with her skin and scalp. Perfumes, dyes, certain proteins, nuts, etc etc can set her off. She also has dry, frizzy, wavy, hair ....so i have to use products that will actually help her hair as well. She takes a quick bath three times a week in water mixed with sea salt and Aveeno oatmeal packets. I know it seems gross to bath only three times a week but as her dermatologist pointed out every day showers or baths with harsh soaps dry out your skin and hair and lead to dryness and irritation. The sea salt/ oatmeal combo seems to help her hair retain moisture but is mostly because I cannot use soap or cleanser on her skin so the oatmeal acts as a natural cleanser. I use Kinky Curly Come Clean
shampoo (from naturallycurly.com) or Burt's Bees Baby Shampoo (I get this from Target) to cleanse her hair 2-3 times a week. Neither of those seem to contain anything harsh that sets her skin off. Conditioners are iffy. Some that are scented send her skin into a massive frenzy of itching and redness. The one I have used now for a year that seems to do very well with her skin is TIGI Bedhead Moisture Maniac. (from the local drugstore) I also love this one for my hair and my stonger herbal conditioners like Aubrey Organics are too much for her skin any way. As for stylers and detanglers I use Curly Qs Moist Curls Moisturizer (from naturallycurly.com) and Fruit of the Earth Aloe Vera Gel (Walmart) for her. It is the unscented clear kind of aloe you put on sunburns. Both of these keep frizzies away and you can apply the Curly Qs to wet or dry hair. I hope that helps. I don't experiment to much after I find something that works for her because I don't want to have to take her to the doc for a steroid injection due to a massive outbreak of her dermatitis.
