How to determine your hair type?

You might be overwhelmed by lots of shampoo and hair care products advertisements on media. We all need healthy, silky, and non – dandruff hair yet not everyone really cares whom the products should be used for and know how often should you wash your hair.

Before planning how to treat your hair, make sure to know well your hair type since examinations should always come before treatments. The two simple tests below shall help you choose appropriate shampoos for yourself and set your hair washing schedule.

How to perform the check? Put a single hair in between your two fingers, then rub the fingers together to really feel how thick your hair is.

If you can hardly feel the hair, we could say that you have fine hair.

In case you can feel it yet the feeling is not very clear, then you have got medium hair.

You easily feel that it is thick and rough, it is thick hair.

You had better pick a typical single hair, because, you know, baby hair is much thinner than the other.

The Stretch Test, on the other hand, helps you understand well your hair condition. Get a single hair and gradually stretch it out, from a gently to a little intensely traction.

If it breaks easily and immediately, showing its low elasticity, it shows that your hair is unhealthy and weak.

In case it breaks under strong traction only, your hair should be considered to be healthier.

However, please be notified that hair type may change due to the flexible weather conditions, mental and physical health, or age, hence, you should do those tests again if there is change forecasted.
