How Long Does Hair Grow in a Year

Hair is one part of the body that plays an important role, not only for women but also for men. Therefore, even though it is only visible from the outside, it is still necessary to maintain healthy hair.

In addition to branching, another characteristic of healthy hair is that it does not fall out easily. You don't have to worry about your hair falling out every day. Everyone will experience hair loss of 25-100 strands per day. And this is normal. Hair on the scalp will grow about 0.3-0.4 mm per day or about 6 inches per year, but everyone has a different hair growth phase. Hair growth and loss also occur randomly, unaffected by the seasons.

Hair growth has several phases, the following is an explanation.

First Phase: Anagen. 

Every part of your body will go through a different phase of growth, including every strand of hair on your head. Well, specifically for hair, the journey starts from the anagen phase. What is the anagen phase? This phase can be broadly interpreted as a phase where the follicle will encourage the hair to continue to grow slowly, but not stop. This process can take up to 3 to 5 years. 

Second Phase: Catagen. 

After completing the first phase, your hair will go through a transition period which is also known as catagen. In this phase, the follicles will shrink and your hair growth will also be stunted for about 10 days until it finally stops growing. This phase can be considered the last time your hair grows. The reason, although separated from the follicle, each strand will remain in the hair. 

Third Phase: Telogen. 

When the catagen phase is complete, you will enter the telogen phase or rest period. In this phase, each strand of your hair will not grow again and will remain the same size for about 3 months. When hair forms in the follicle and is ready to grow and replace it, then the telogen phase ends and you will enter the final phase, which is exogenous. 

Final Phase: Exogenous.

The exogenous phase is the final journey of each hair strand. It should be understood, this phase is also known as the phase where every strand of your hair will fall out. According to the American Academy of Dermatology (AAD) Association, 50 to 100 hair loss is normal. Later, the hair that has fallen out will be replaced with new ones, which will pass through the first phase (anagen). A new problem will arise when your hair is difficult to grow back or fall out in too much amount (> 100 strands). If this is the case, there may be a problem with your body, whether it is related to your health or the food you eat. Then, another reason could be that the product you choose is not a shampoo that makes your hair thick.

Those are the three hair growth cycles that you should know. So you don't have to worry about normal hair loss. But if your hair loss looks severe, it's a good idea to start doing maximum hair care. You can start doing regular hair care, using special shampoos and conditioners to deal with hair loss.
