According to Curejoy Expert James Dudley
Hair is produced by hair follicles situated in the deepest layer of the skin and is collected mostly of dead protein and pigment. The quality, thickness and texture of the hair are reflected in the changes in the body’s metabolism.
Few signs of what your hair and scalp say about the health:
1. Gray hair:
Gray hair generally considered a sign of poor health, thyroid issues, though anaemia, vitamin B-12 deficiency, and vitiligo can cause premature graying.
2. Dry/limp hair:
Many factors can make dry hair, including hair dyes, hair blowers, and swimming in chlorinated water. But a significant change in texture that leaves hair feeling finer, with less body, can be an indicator hypothyroidism.
Some people conclude that their hair is thinning because it feels as if there’s less of it, but the thinning is due more to the texture of the hair itself becoming finer and weaker than to individual hairs falling out (though that happens too).
Other signs of hypothyroidism include: fatigue, slow heart rate, weight gain, and feeling cold all the time.
In some cases, the eyebrows also thin and fall out.
3. Scaly patches on scalp:
When a thick crust forms on the scalp, this usually indicates psoriasis, which can be distinguished from other dandruff-like skin conditions by the presence of a thickening, scab-like surface.
4. Receding hair:
It just not happens to older men; it can be caused by a lack of diet nutrients. Hair can retreat as a result of crash diets. If you cut corners it will be reflected in your hair. It will look lack lustre, fall out and reflect your overall ill health.
However, decrease hair is also common among women with Polycystic Ovary Syndrome. Women with PCOS can develop facial hair and new hair on their arms, chest and buttocks, yet their hair recedes on the scalp.
5. Tiny white bumps at roots of the hair:
Presence of this suggests that it is temporary hair loss rather than the more serious male/female pattern baldness. Any medication that interferes with hormones can cause this type of hair loss; the list includes birth control pills, Accutane for acne, and prednisone and anabolic steroids.
6. Hair loss:
Falling a few 100 strands of hair every day is a normal occurrence. But you notice considerably more hairs in your brush or on the towel after you shampoo — or when hair appears to be coming out in clumps —then it is not normal. One common reason would be a sudden psychological or physical stressor, such as a divorce or job loss. One more reason is having a high fever from the flu or an infection. Diabetes can also be the cause hair to thin or start to fall out suddenly.
Some diabetes experts say sudden hair loss should be considered an early warning sign that diabetes is affecting hormone levels.
7. Short layers on top:
Shorter layers on top are caused by breakages in new hairs growing through it. If it is happening to you, it’s probably you don’t have enough protein in your diet. This make the hair weak and leaves it less resistant to heat and chemicals.
