Classification by Structure
Hair structure (i.e. how thick or thin it is) is determined by the size and shape of the follicles. This is due to ethnicity and genetic factors. A person with thin skin often has thin hair type and vice versa. A direct correlation between the thickness and natural pigmentation is also found: blondes have the finest hair, while brunettes have the thickest. The shape of hair (straight or curly) has no effect on its structure.
1. Thick hair is very strong, it looks heavy and full. Those with thick hair often complain how it’s difficult to tame and styles their strands. that it is difficult to “subdue”. In addition to thick hair being difficult to subdue and fix as desired, it is even more challenging to curl! And after all the effort, it returns to its natural form fairly quickly under its own weight even after being straightened. In order to dye thick hair, it requires prolonged exposure to the dye so that chemicals have time to penetrate into the structure. But thick hair copes with dyeing, bleaching, and perms easily — its structure allows it to maintain a healthy and well-groomed appearance without becoming damaged.
2. Medium-thick hair is the most manageable and pleasant hair type to care for. This is the most common type among European women. Most haircuts suit those with medium-thick hair and after being styled it lasts for a long time. It is flexible and easy to dye to the desired color and withstands perming and straightening well.
3. Thin hair often disappoints its owners by the lack of volume. Even if there are a lot of follicles, it seems to be sparse because of its thinness. It is fragile and often prone to splitting and needs regular moisturizing. Experts recommend avoiding the use of blow dryers and flat irons for this type, as these can cause the hair to become thinner. This type is easy to dye, but it can severely be damaged and lose its healthy appearance under the influence of dying.
