I can't deny that the ladies of BGC know what they are talking about even if they can be controversial. There are some exceptions but for the most part the info is universal for tight curly/coily hair. Their observations of how shampoo works is different from what is found in cosmetology textbooks and what hairstylist like Chris the Blowout Professor on YT talks about. I guess you have to change the rules a little with tighter curled hair.
For instance, coarse hair would use moisturizing shampoos because the oils on the scalp don't weigh the hair down as quickly as fine hair. Its not about how dirty the hair is per se regarding product usage. Its about the hair texture (fine, medium or coarse) and how oily it gets. Then use specialty shampoos for specialty reasons much like when one uses deep conditioners.
I personally don't get as many days of a clean scalp when using only moisturizing shampoos. I recently went a full week before CCSing. At the 7th day mark, my scalp was waxy but no flakes or sores. That was made possible because I shampooed 3 times with AG Balance and then went straight to conditioner. This is what I would consider the exception. BGC shampoo rules apply more to my hair than to my scalp. My mom can go months without washing her hair and her scalp is great. However, her hair is fine like mine. We just have different surface textures and that too makes a world of a difference.
