OK I will admit that as an AA woman with 3 bi-racial kids( d/h is CC) I am LOL over this issue! Not because its "funny" but look girls...it IS funny. I am also able to laugh at myself because I started out using *MY* hair care products on these kids who BTW have varying shades of cotton candy like hair. I turned my oldest daughter into a little syrup head one weekend 
before a bi-racial co-worker rescued me.
OK here is another approach to "black hair care." #1 Ditch the shampoo/ rinse routine. #2 Please know that our hair is extremely dry and brittle. It is the opposite of "CC" hair in that it does not get oily on its own. We have to oil our hair almost daily. It is a good thing to do this; it strengthens the hair, avoids breakage, helps it grow and avoids the frizzes. #3 Go to Walmart, Krogers, 7-11 anywhere hair care products are sold and buy a Bergamont/ Conditioning Hair Dress- type scalp GREASE. Wash and dry the hair, apply the "grease" directly into the scalp by parting it into small sections and rubbing it in. Apply a liberal amount of the grease to the hair itself and brush it to distribute it all over; comb and style as usual. You may even consider using a small amount of Gel to help it lay flat but use it only after the grease is used as it can be drying too. Prostyle makes a great Gel, and Blue Magic makes an excellent Conditioner/ Hair Dress (grease). As the child becomes older (age 2-3 and over) you can do the Just for Me perm for kids and it will relax the hair without harsh chemicals and make it so easy to comb and style, or perhaps a flat iorn approach to smooth it when the child is able to sit still.
As far as shampooing goes once every 2 weeks or so is enough. The hair grease will stop the flakes. The use of leave in conditioners usually adds to the dryness and frizzes; so does too frequent applications of water; remember, or hair is normally dry and brittle. Please let me know if I can be of further help...MissyM
