Why Is My Hair Thinning

A very common question professional haircare experts are asked is "Why is my hair thinning?" There are several possible answers, which we're about to explain in uncomplicated terms so that you can find the best solution for thicker and healthier-looking hair.

Why is my hair thinning?

Hair thinning is not necessarily age-related, although it is common to see a gradual thinning of hair as we grow older due to our scalp stem cells weakening and slowly ceasing hair production as we age.

Before you can understand why your hair is thinning, there are some important distinctions to make. There is a difference between a) a change in the texture of your hair, b) a reduction in hair growth, and c) hair loss/hair dropping out.

Changes in hair texture

The texture of the hair can evolve throughout our lives due to changes in the hair follicle (where the hair fibre is produced). This can be caused by damage over time, perhaps due to repeated pulling or medication. The structure of already-existing hair fibres can also be permanently changed as a result of over-processing, where the fibre loses its natural form (such as curls), becoming weaker and thinner. Hormonal changes, such as pregnancy or the menopause, can also affect the natural texture of the hair, resulting in thin hair.

Reduction of new hair growth

A reduction in hair growth could also be the reason behind your thinning hair. We shed about 100 hairs per day, which might sound a lot, but the human head is estimated to have around 100,000 hairs at any one time, although this varies considerably depending on factors such as age and genetics.

Hair loss vs thinning hair?

Is your hair really thinning or is it actually falling out? Literal hair loss, where pre-existing hairs fall out before they should naturally, can be due to several reasons. Medical treatments (chemotherapy) and conditions such as alopecia can be behind the phenomenon. The pulling out of hair, or consistent tension on the hair itself has also been connected with losing hair as a result of weakened follicles that hold the hair in place.

How can I get thicker hair? 

If your hair's thinner appearance is due to a change in texture (weaker, finer-feeling hair), hair falling out or a reduction in new hair growth, here's what you should try! The first step is to reduce, if not stop entirely, harsh styling that pulls at the head. Aggressive brushing and hairstyles that create tension on the scalp may be causing excess hair loss and damaging your hair-producing follicles. A way of supporting the growth of new hair could be a great excuse for some pamper time... Regular scalp massages can help stimulate circulation and in turn promote the development of healthy new hair fibres. A head massage also helps the production of natural oils, which moisturise the hair shaft, keeping hair smooth, supple and shiny and reducing dryness, split ends and breakages.
