Interesting conversation. I definitely think that LCHF and other such hair boards are changing the image and future of Black hair care for the reasons that have already been stated.
To humbly add: I think these boards will have an economic impact on the hairdressing industry, specifically, the vocation of being a hairdresser/hair stylist. In a conversation with my mom (a LONGTIME, OLD-SKOOL hairdresser), she has noticed business fluctuations because:
--products that only LICENSED hairdressers could get are now available in mass quantities, e.g., special treatments, certain relaxer brands, even weaving hair!
--people are doing their own hair more, partly because of the above and don't want to spend the money.
--people are wearing braids and other types of styles as they become more "acceptable" in the workplace
--(some) hairdressers are simply not listening to their clients about what they want for their hair and now that people have expanded options for hair care, they vote with their feet.
--people are growing out of their relaxers and now have need for different services and there are fewer hairdressers trained or taught (IN BEAUTY SCHOOL) on how to deal with naturally textured hair. A smart hairdresser will see this trend and EXPAND their skills and meet this growing market demand for more natural hair stylists.
