Hair does hair grow

Ever wondered how your hair grows, what causes it, why your hair breaks and what is your hair made from? Here is a little insight to understand how to get your hair in a healthy condition.

Growth cycles

The three stages of hair growth are the anagen, catagen, and telogen phases. Each hair on the human body is at its own stage of development. Once the cycle is complete, it restarts and a new strand of hair begins to form. The rate of hair growth is about 1.25 centimeters or 0.5 inches per month, or about 15 centimeters or 6 inches per year.

Anagen phase

The anagen phase AKA the growth phase. It begins in the papilla and can last up to six years. Genetics determine how long hair will remain in this stage. The longer the hair stays in the anagen phase, the faster and longer it will grow. During this phase, the cells in the papilla divide to produce new hair fibers, and the follicle buries itself into the dermal layer of the skin to nourish the strand. About 85% of the hairs on one's head are in the anagen phase at any given time.

Catagen phase

The catagen phase begins the moment the anagen phase ends, and this is determined by the body itself. The catagen phase allows the follicle to, in a sense, renew itself. During this time, which lasts two weeks, the hair follicle shrinks due to disintegration and the papilla detaches and "rests," cutting the hair strand off from its nourishing blood supply. Ultimately, the follicle is 1/6 its original length, causing the hair shaft to be pushed upward. 

Telogen phase

During the telogen, which is also known as the resting period the hair can rest for up to two months. 15% of ones hair is in this phase. In this phase the epidermal cells lining the follicle channel continue to grow as normal and may accumulate around the base of the hair, temporarily anchoring it in place and preserving the hair for its natural purpose.

At some point, the follicle will begin to grow again, softening the anchor point of the shaft initially. The hair base will break free from the root and the hair will be shed. Within two weeks the new hair shaft will begin to emerge.

The anagen phase begins again once the telogen phase is complete.this is the result of hairloss.





Miniaturization is the technical term given to the shortening of the Anagen phase of the hair growth cycle. For many people the length of the Anagen phase shortens every cycle resulting in hair growing slower.

Many treatments work by increasing the duration of the Anagen phase or reducing the resting phase.

Excessive hair shedding

When the hair enters the resting phase early it results in excess shedding and ultimately noticeably thinning hair. This does not become apparent until approximately 50% of hairs have been shed. This is because each hair is in a different stage of the hair growth cycle which can take years.

It is normal to shed around 100 hairs per day so identifying excessive shedding is difficult. 

What influences healthy hair growth

there are plenty of factors that influences hair growth. From medical diseases, medical treatments, stress, malnutrition and genetics.



As we age we lose the number of follicles per square centimeter and the hair also thins with age, causes your bold look at 80.



Some medicine have side effects that influences hair growth negatively.

Poor diet

Your diet must consist of protein, vitamins and minerals. These are very important for optimal hair growth and your hair needs these ingredients. Malnutrition will lead to long term hair problems.

Hormonal change

Changes in your hormones, especially in menopause will cause a change in hair growth and even an increased loss of hair. 


Birth control

The pill is the most common form of contraception in women; a mixture of progesterin and estrogen carries an occasional side-effect which affects healthy hair growth in those who have a hereditary medical history of hair growth problems.


Hair sprays, dyes, straighteners, blow dryers etc all damages hair and supplements needs to be taken to help balance these hair destroying habits. 


Smoking decrease blood circulation which your follicles need to thrive. Smoking will damage your hair.



Poor hair health:

 Traction Alopecia is caused by excessive pulling or stressing of the hair strand at the root and is often seen in women with tight braiding.


Telogen Effluvium is the  temporary hair thinning from any area of the scalp and is common post pregnancy, after a period of stress or hormonal changes or as a result of poor diet. The hair follicles, go into a resting phase for months. After that hair tends to fall out in chunks, which is frightening to many people. Luckily this is in most cases temporary.


Trichotillomania is an anxiety disorder where people pull out their hair. When the need to pull becomes too great people will pull on the hair until it is tugged out at the root.
