The way to grow black hair faster is with protective styles, moisturizing products and regular trims. Black hair grows at the same rate as all types of hair. However, because of black hair's curly shaft, nutrients and oils may not get to the hair, and that can cause breakage.
Start with a good daily moisturizer that nourishes the ends of hair as it grows. Use moisturizing shampoos and conditioners during regular washings, and get routine trims every six to eight weeks. Although trimming seems to counter the effort of growing hair, trimming stops breakage and damage from traveling up the hair shaft.
Limit the use of heat-styling tools such as blow dryers, curlers and flat irons; they can damage hair. Manipulate hair as little as possible when combing, brushing and styling.
Practice simple protective styles, such as up-dos, to keep the ends of hair from rubbing against pillowcases, clothing and even furniture. Use a satin scarf or hair bonnet to cover hair while sleeping to prevent breakage as well.
Maintaining a healthy lifestyle also helps nourish black hair -- and any type of hair. Eat fruits and vegetables, drink plenty of water and exercise. People who eat badly and who do not get enough vitamins risk having hair that is dry and broken.
