According to Ladies' Home Journal, a comb attachment should always be used to blow dry African-American hair, and even then it is best to allow it to partially air dry first. This partial drying will allow minimal combing and pulling on the hair while blow drying and reduce breakage. African-American hair is more brittle than other hair, so it requires special steps to protect it.
Ladies' Home Journal states that several different steps are necessary to protect longer African-American hair. Washing should be done no more than once a week as exceeding this could dry it out and increase its brittleness. Because of the highly curly and kinky nature of African-American hair, oils do not travel its length easily, and so it rarely becomes truly oily. This dryness means that, African-American hair must be frequently moisturized. It is important to limit the use of conditioners for dry and damaged hair, however, as these often contain protein that can actually harden hair with excessive use, leading to brittleness and breakage. Hair weaves are also a consideration for protecting African-American hair, as this removes the need for direct styling. Sewn weaves are superior to glued weaves because the glued type can tear hair when removed.
