When I was their age my regimen consisted of shampooing and conditioning my hair followed by a pressing with a hot comb (comb heated up on the stove) This method of styling my hair would often result in my ear or neck getting a burn here and there. The press also only lasted for a few days because  of the extreme heat and  humidity in my home town. For these girls their regimen consist of shampooing , and conditioning, no need to deal with hot combs, regular combs, picks or brushes. The weather is also of no concern to these girls, their locks aren’t afraid of rain!
