Thinning of hair is normal, but it can be slowed down

New Delhi: Hair thinning or hair loss is a common phenomenon and worrying about it only worsens the problem. But at times it can upset a person emotionally, impacting both his or her confidence and identity. Rob Smith, Senior Principal Hair Care Scientist, at Dyson, gives a breakdown of the causes of hair thinning and effective ways to combat it.

The four phases of the hair growth cycle:
Anagen: It lasts two to eight years. This first phase of the cycle is where hair is actively growing. The cells in the root of the hair add to the hair shaft. At any time, 80-90% of the hairs on a head are in the anagen phase.
Catagen: It is usually four to six weeks long, the catagen phase is a short phase which occurs at the end of the anagen phase. The hair strand detaches from its blood supply.
Telogen: It lasts two to three months when the hair is neither growing nor falling out.
Exogen: It happens when the hair sheds and falls out, which can last two to five months. On average, people lose between 50 to 150 hairs each day.
Thinning hair can occur for many different reasons. Age and stage of life can affect our health hugely and cause a change in the condition of our scalp.
These include:
Pregnancy: During the second and third trimesters of pregnancy, the number of hairs in the active growth phase, known as anagen, increases. After the birth, hormonal changes can lead to follicles moving to the catagen or telogen states, resulting in post-pregnancy hair shedding.

Emotional stress: A sustained level of emotional stress after a serious life event, such as bereavement, can cause hair follicles to shift from the growing phase to the resting phase. After two to three months, this can often become more noticeable, even if it is temporary, with more hair thinning and fall out.

Getting older: Many people experience hair thinning during the ageing process. The rate of hair growth slows as your body ages, and each hair strand becomes smaller with less pigmentation – which is why people begin to develop grey hair.

Illness: Thinning hair and hair loss can happen during illness. One such effect is an autoimmune condition called alopecia areata, a disease that develops when the body’s immune system attacks the hair follicles as part of its defence system, causing hair loss. This can happen anywhere on the body. Thinning hair and hair loss can occur during treatment for illness too. The main example includes cancer treatment, specifically during chemotherapy.
Hereditary hair loss: One established reason for hair loss is genetics, where hair loss isn’t the result of a disease, but a natural combination of hereditary genes, hormone levels, and the ageing process.
Hormonal effects: The hair cycle and hair follicle structure are highly affected by various hormones.
These include androgens such as testosterone, sex hormones such as estradiol, and thyroid hormones such as thyroxin and cortisol which are released by the adrenal glands as a stress response.

How to reduce or treat thinning hair
Losing hair can be a difficult experience. Hair loss and thinning can stem from many different reasons, often exacerbated by lifestyle factors including high-stress levels, an unbalanced diet, iron deficiency and sudden weight loss. But there are some things you can do. To maintain healthy, steady and effective hair growth, it’s important to prevent hair thinning from an early age.

Things you can do to promote hair growth include:
Eating a healthy and balanced diet. Staying active reduces stress and stimulates endorphins. Embracing relaxation techniques such as meditation and massage. Improving the balance of your work and personal life. If you are suffering from dietary or health deficiencies then the use of supplements can have a benefit on hair growth, but not all do so. In fact, in some cases consuming too much Vitamin E or Selenium can have the effect of actually increasing hair loss.

If you’re interested in which shampoo or hair thinning treatment to use, the first step is trying to identify the source of the problem, to establish why your hair is shedding or falling out.

Many shampoos claim to reduce hair thinning and promote hair thickness, as well as improve the shine and the general appearance of your hair. It’s important to research the formulas and check the science behind them. Caffeine for example has a growing body of evidence14 in promoting hair growth.
There are also scalp treatments available, one of the more common actives recommended being topically applied Minoxidil15, which has been shown to increase hair density for some conditions.

It is worth mentioning however that even proven treatments don’t work for everyone. Can hair grow back after thinning or baldness? In many cases, hair thinning can be resolved or improved by a variety of techniques already mentioned above.
However, if the hair follicle has stopped producing any new hair strands over a long period, new hair is unlikely to grow there especially if the underlying causes remain.

How to make hair look thicker:
If your hair continues to thin, there are a range of options to consider that can help hair appear thicker and fuller, some of these can be quite invasive so make sure you understand the risks and benefits.

These include:
» Blow drying hair in an upward motion
» Wigs and artificial hairpieces
» Hair transplants
» Light therapy
» Tattooing your hairline

How to hide thinning hair at the front
Creating an illusion of thicker hair and fuller volume can also be an effective way of approaching the loss, especially if you’re trying to preserve your self-confidence. Hair care products such as styling mousses can help add volume and body to your hair, supporting you to feel more confident.

Creating a middle part to drape hair over both sides of your face will help to create the illusion of fuller hair. A similar technique, used by salon professionals, is to add layers to your hair to add volume and provide definition.

Hair thinning is normal
Hair thinning can be a difficult process to go through, but it is a natural part of life. Depending on the reason for your hair loss and thinning, there are many ways to slow the process and preserve your hair. It is worth talking with a Trichologist for advice in finding a solution that works for you as an individual.
