The B complex vitamins are particularly important to hair health and beauty. Deficiencies of biotin, folic acid, pantothenic acid, and PABA can lead to a loss of colour and there has even been success in reversing the greying process by giving supplements of these nutrients, particularly doses of PABA. One researcher claims to have restored colour to greying hair in 70 present of cases with PABA.
A lack of any of the B complex can result in hair troubles and losses. Vitamin B1, B2, and B12 are particularly important in invigorating lacklustre hair, clearing dandruff, scaling, redness of the scalp, and hair loss. Vitamin C is important too, because it maintains the health and strength of the capillaries supplying the hair producing follicles with nourishment. If your levels of vitamin C are too low, this results in perifollicular haemorrhages, in which these capillaries break and bleed, resulting in improper nourishment to the papillae.
How fast your hair can grow depends on adequate, but not too much protein, since more than adequate amounts can deplete your body of the minerals it needs. It is the right balance of nutrients that is most important. The condition of your hair is greatly affected by medicines that you take; antibiotics, sulpha drugs, aspirin, the Pill, diet pills, tranquillizers, thyroid pills, cortisone, anticancer drugs, and even cold remedies are a common cause of brittleness, dullness, breakage, and loss. Hair follicles are ultrasensitive to hormones. If you are taking a birth – control pill and having trouble with your hair, you might consider changing brands to see if it improves, as well as taking supplements.
