What Fitzpatrick skin types typically have a deeper root system?

Fitzpatrick skin types IV to VI typically have a deeper root system due to the increased melanin content found in these skin types. These skin types are generally classified as medium to deep skin tones and have more pigment, which offers some degree of protection against ultraviolet (UV) radiation. This higher melanin concentration not only contributes to a richer skin tone but also influences hair follicle depth, leading to a deeper root system.

In contrast, Fitzpatrick skin types I to III are characterized by lighter skin tones with less melanin, which often corresponds to shallower hair follicle roots. These lighter skin types are more susceptible to sunburn and have lower natural protection against UV exposure, impacting hair health and root depth. The classification of skin types is vital in understanding how hair and skin react to various treatments, as well as in preventing damage during procedures.
