Hair and Scalp

Hair Analysis Not Reliable

There is no question that a chemical examination of hair does offer information as to past toxic exposures. The presence of highly poisonous heavy metals like arsenic and thallium found during hair analysis has been forensically useful. But care must be taken in collecting evidence, and the interpretation of the facts can be tricky.

Does a Scalp Massage Help?

Some people enjoy a good scalp massage, which may have certain sensual benefits. However, there is no medical benefit to be derived from them.

Surprising Side Effects of Medications

Many drugs can inhibit hair growth. Since it takes about two weeks for a hair two grow from the root to the follicular orifice, it may be difficult to determine which drug may be responsible for suppressing hair growth. The following is a list of categories of drugs potentially likely to inhibit follicular function: anticancer drugs, anticoagulants, anticonvulsants, anti-gout medications, antithyroid agents, beta-adrenergic blockers, tricyclic antidepressants, and oral contraceptives.

Overstyling Weakens Your Hair

Drying, coloring, straightening, ironing, combing, curling, twisting, and pulling can damage hair.

Traction Alopecia Damages Follicles

There are a number of ways we can damage our scalp hair in an effort to improve its cosmetic appearance. One of the most common conditions is called traction alopecia, which if persistent, can result in permanent hair loss. This occurs when chronic constant tension is applied to the hair shaft. This damages the follicle and inhibits hair growth. Certain hairstyles, such as tight ponytails, braids, and cornrows, are likely to produce this condition.

Premature Gray Hair Is Genetic

The loss of hair pigmentation is almost universal as we age. Early and localized loss of hair color can also be due to a number of conditions that ought to be diagnosable by most dermatologists.

A Hair- and Heart-Healthy Diet

There is no food that will provide all of the necessary nutrients for hair growth. But diets high in fish, nuts, fruits, and vegetables are likely to be beneficial. Direct specific questions to professional dieticians.

Nutrients Are Important for Healthy Hair

Along with appropriate exercise and sleep, a well-rounded diet will produce a healthy body, which is manifested in beautiful hair. Poorly conceived dieting and protein restriction will diminish and damage hair growth.

Avoid Sun Damage to Your Hair

Since hair is composed of dead protein, it is important maintain it correctly to optimize its appearance. Having luxuriantly abundant hair is a clue to general good health. Because hair does not repair itself, it is susceptible to environmental degradation by sunlight, dryness, chemicals, and physical trauma. An excellent haircut, avoiding chemical treatment, hats, and post-shampoo conditioners can improve and promote healthy-appearing hair. On the other hand, you can always shave the scalp, which for some men seems to work well.

Female-Pattern Baldness

Female hair loss as opposed to that in the male can be a devastating cosmetic problem. Most of the time, classical female pattern balding is due to a genetic predisposition enhanced by hormonal factors. Rarely, it can be a sign of other serious medical problems. It may be necessary to visit a physician to determine if any specific cause can be found.

Genes Cause 90% of Male Hair Loss

Normal hair thinning (resulting from follicular miniaturization) involving the temples, frontal hairline, and crown of the scalp, known as "pattern alopecia," occurs in almost everyone as they age. Its extent depends on genetic and hormonal factors. In women, this is usually seen after menopause. In men, it occasionally occurs as early as the mid-20s. There is no cure for this condition, but topically applied minoxidil (Rogaine) and oral finasteride (Propecia) can promote hair growth in some patients. Hair transplantation is used to camouflage this type of hair loss.

Alopecia Areata Attack

Alopecia areata is an autoimmune disease where the body attacks a group of hair follicles usually no larger than 1 inch or 2 in diameter. The hairless skin otherwise appears entirely normal. Though the condition usually resolves spontaneously, occasionally it can involve the entire scalp or even every hair on the whole body and be permanent. There is no reliable curative treatment, but frequently a steroid solution can be injected into the bald area to suppress the inflammatory component for a time.

Telogen Effluvium Causes

Occasionally, a large proportion of the scalp follicles begins to grow synchronously and so are in the same phase of the hair cycle. When this occurs and these hairs are shed at the conclusion of the telogen phase, it is perceived has extensive hair shedding. A variety of things seems to predispose to this "telogen effluvium," which include pregnancy, severe illnesses, certain drugs, and emotionally traumatic situations. Once the provocation resolves, the hair almost always begins to grow normally again.

You May Shed More Hair Than You Think

All hair follicles, including the 100,000+ on the scalp, exhibit a growth cycle. This cycle is composed of growing periods, quiescent periods, and regression periods. There are many factors that affect the lengths of these periods, including hormones, anatomical location, genetics, general health, medications, and perhaps the psyche. About 90% of scalp hairs are in the growing phase (anagen), and about 10% are normally in the resting phase called telogen. Each follicle grows and replaces its hair independently.

Yellow Dandruff?

Probably the most common rash present in adults is seborrheic dermatitis. This disease typically affects the skin of the scalp, ears, forehead, face, and occasionally the mid-chest and/or back. When the scalp is involved, the red scaling plaques produce excess dandruff. Even though this condition is exceedingly common, there is a poor understanding of its cause. Although it is incurable, it is easily treatable with a variety of safe and effective topical medications, including topical steroids, zinc pyrithione, selenium sulfide, topical antifungals, and tar preparations found in medicated shampoos.

Dandruff Treatment Tips

Occasionally, if there is excessive scaling in the scalp, it may be necessary to change certain habits to diminish the amount of dandruff. Infrequent shampooing alone is sufficient to produce what appears to be excess dandruff. The accumulated flakes of skin produce an unpleasant appearance on the hair and clothing. All that needs to be done is to shampoo more often. If the origin of the dandruff is a scalp disease, using a medicated anti-dandruff shampoo is often helpful. If this fails, it may be necessary to seek a professional's opinion.

White Flakes Are Not a Health Risk

Dandruff is the name given to skin scale that the scalp produces. Since part of the function of skin, including that on the scalp, is to produce a semi-impenetrable horny barrier to protect us from the outside environment, a few scales are perfectly normal.

Is Bad Hair Related to Bad Health?

Your hair is a product of your body and is produced by hair follicles situated in the deepest layer of the skin. It is composed mostly of dead protein and pigment. Changes in your body's metabolism can be reflected by changes in the quantity, thickness, and texture of hair. The anatomical location of the hair follicle plays a major role the variety of hair produced.
