Hair Types and How often You Should Wash Them

In a world where there are different kinds of people with different colors, cultures, and climatic environments, as expected, our hair type differs too. Hair types and how to determine the frequency of wash days;

1. Thin-fine straight hair type

Having concluded the opinions of different dermatologists, thin-fine straight hair requires more washing attention than any other type of hair. This is because the thin-fine straight hair is easily prone to oiliness.

Therefore, it quickly gets dirty and needs to be washed very often. Going a day or two before washing is just perfect for people with this hair type.

2. Curved or curly hair type

For this hair type, washing twice a week is a good practice because a curly type of hair seldom gets oily. Washing this type of hair frequently can make it dry or frizzy which can cause critical damage to such hair.

3. African-American hair type

African American hair type does not require daily washing. This is because such hair type is naturally dry hair. Frequently washing such hair takes away the little oil the skin provides to moisturize the hair. For such hair washing once weekly or every other week is perfectly fine.

 4. African hair type

African hair type doesn’t get dry easily but the texture is sort of coarse, so washing the hair too often can damage such hair type. People with African hair type hardly leave their hair undone.

Therefore the need to wash their hair only arises when they lose out on the hair they made. Washing your hair once in two weeks is not a bad idea. Truthfully, the African hair type can get away with washing their once or twice in three months.

5. Thick hair type

The gist is that thick hair follicles hardly build up oil in the hair. This means that the thick kind of hair isn’t very oily. Hence, washing your hair very often can cause more harm to your hair than expected. Try washing your thick hair just once a week.

However, there are always exceptions i.e, some thick-haired people experience oily scalp or itchiness.

So, getting a specific hair wash or shampoo that is mostly for follicle clearing and zap inflammation can help reduce itchiness and the oily follicle. It helps to clean the root without feeling frizzy.
