General Information about Hair care
Taking care of the scalp skin is an important part of hair care as the scalp skin holds the hair roots and follicles which are the living parts of hair. Scalp skin should be kept healthy and if not regularly cleaned can lead to bacterial infections. There are other disorders that may not be due to bacterial infections like dandruff or hair lice and there are also infections that affect the hair itself. Split ends (trichoptilosis) occur when the hair shaft splits and must be trimmed as there is no cure for split ends.
Climactic changes or a shampoo with high detergent base could lead to a flaky, dry scalp. An itchy scalp can be caused by allergic reactions to hair products. A greasy scalp may lead to dandruff, eczema, dermatitis or scalp psoriasis. Scalp psoriasis is considered to be inherited and appears as red lesions covered with scales on the scalp. Dermatitis is inflammation of the skin and eczema is a form of dermatitis causing red, flaky skin that may crack and also cause blistering.
Examples of Drugs.
Excess sweat and oil as well as unwanted products can be removed from the scalp and the hair through regular washing, often done using a shampoo. A conditioner can be used after shampooing to smoothen down the cuticle layer of hair which may have been roughened by shampooing and also protect the hair from damage.
Dandruff may be removed by regular shampooing with medicated shampoos designed specifically to deal with dandruff. Skin moisturizing products or olive oil can be used to deal with dry flaky scalp or a milder shampoo may help. Changing the shampoo or using anti-itching products like Cortaid could help with an itchy scalp. Anti-lice hair cream rinse and shampoos and a good metal lice or nit comb can help with removal of lice.
Typical Directions of Use.
Shampooing should be done while gently massaging the scalp and all remnants must be removed by thorough rinsing. Conditioners should be applied to the hair after shampooing and left for a few minutes and rinsed off. Leave-in conditioners may be gently massaged into the hair after towel-drying the hair. Anti-itching and skin moisturizers may be massaged into the scalp at night and washed off in the morning. While using anti-lice products carefully follow instructions on the label leave the product in the hair for prescribed time and wash off. Comb out the lice and nits from the hair using the specialized comb.
Possible Side Effects.
Daily shampooing may lead to eczema in people with dry scalps so shampooing every two-three days may be ideal for them. Contact with eyes while using hair products may lead to irritation. If instructions on the label are not followed it may lead to hair damage. Lesions must not be irritated or scratched further or it could cause infection.
Although hair problems normally respond to over-the-counter remedies and better care, if the condition persists a dermatologist or physician must be consulted to avoid further damage.
