Why is Afro-type hair more often dry?
Our experts answer your most frequently asked questions.
Curly or coily Afro-type hair is naturally more dry than Caucasian hair (supple) or Celtic hair (straight). It is less rich in essential fatty acids, and the pilosebaceous follicle produces much less sebum (as in fact the sebaceous glands are smaller). It is also less hydrated since it has a lower water content.
This type of hair is also often subject to more external aggressions than Caucasian or Celtic hair. As this hair type is harder to detangle, curly or coily hair is often brushed more severely. Furthermore, straightening or smoothing is more aggressive, as much higher temperatures are needed for a good result. These treatments will eliminate what little natural sebum is present.
Afro-type hair is therefore more fragile. To maintain it, you should use hair care products with creamy or oily textures to hydrate, nourish, detangle and protect the hair shaft as much as possible.
