Shedding hair is a healthy process because it allows new hair re-growth on the scalp. Normally 10 percent of our hair is in the telogen (resting) phase. After 2 or 3 months, the hair fiber that were in the resting phase falls out to allow for new hair to grow in its place.
Any disturbance in the normal hair growth cycles can lead to excessive hair loss. Some of the common causes of hair loss are discussed below:
Imbalance in the level of hormones
Hormonal imbalances are the major reasons for hair loss in both genetic and other types of hair loss. In women hormonal imbalance is one of the most common causes of hair loss. Hormone related hair loss generally occurs when there is an excess of the testosterone hormone. The excess testosterone is converted to DHT by an enzyme called 5 alpha-reductase present in the hair follicles. DHT (dihydrostestosterone) miniaturizes the hair follicle and results in thinning of hair. The hair follicle dies and hair fiber finally falls out.
Thyroid hormones also play a major role in hair growth. Any disruptions in the normal production levels of thyroid hormones can be a cause of hair loss. Hair follicles contain receptors for thyroid hormones and are very sensitive to the levels of thyroid hormones in the blood. Both too little and too much of thyroid hormones can push hair follicles into a dormant telogen state. With hair prematurely going into the resting (telogen) phase at a faster rate, hair loss problems become more acute.
Nutrition in hair loss
Lack of proper nutrition is also linked to hair loss. Hair growth is a constant metabolic activity which requires adequate food supply. Without sufficient food supply to follicles, their normal metabolic activity decreases eventually resulting in diffuse hair loss.
Apart from regular intake of food, an adequate presence of minerals (silica, zinc, iron, calcium, and magnesium etc.) vitamins ( vitamins B, vitamin C and vitamin E etc. ), protein and amino acids in the diet are necessary for healthy hair growth. Some of the nutrient supplements are also required for proper functioning of hormones that are responsible for androgen metabolism. In addition to minerals, fatty acids are essential in the food to promote a healthy growth of melonocyte cells.
Stress and hair loss
Stress is also among the common reasons for increased hair loss. Research is still going on to find out the exact mechanism of how stress affects normal hair growth. Experts generally take the view that the hair follicles are surrounded with a network of nerve cells. Any disruption in the normal nerve cellsí signals leads to adverse effects on the hair follicles and their growth.
Hair loss induced by stress becomes more evident sometime after you find the texture of your hair becoming dull and lifeless. Stress also seems to affect the sebaceous glands which produce more sebum to make them oilier. The hair follicles ages early, stop growing and enter the resting (telogen) phase.
The best thing about this stress-induced hair loss is that it is temporary in nature and hair growth will be fully restored once the reasons for the stress fade away.
Harmful Chemicals present in hair care products
Synthetic hair care products generally contain harmful chemicals which can have severe, negative effects on hair follicles.
Propylene glycol (PG) is a liquid substance used in the formulation of hair care products and other skin cosmetics. Isopropyl is used in hair color rinses, body rubs, perfumes cosmetics and unconcentrated essential oils. It is basically a toxic solvent and denaturant, potent enough to transform the composition of other chemicals.
Sodium lauryl sulphate (SLS) is a detergent used in shampoos, hair conditioners and other toiletry products. It damages the hair and can cause serious irritation of the skin. Formaldehyde is another poisonous chemical, used in some cosmetics, including shampoos, and conditioners as a preservative.
Adequate care using natural hair care products is absolutely necessary to promote healthy hair growth. Apart from natural products, a disciplined lifestyle combined with a balanced nutritious diet is the key for healthy hair. Here are some natural hair care tips which will help you to achieve a beautiful wave of hair.
