You might have dry scalp from blowdrying your hair. I found that Herbal Essence Shampoo and Conditioner gets rid of dry scalp fairly well.

dandruff is mainly caused by having a dry scalp. it’s just dead skin flaking off. try using any dandruff shampoo and conditioner. they all work pretty well. head and shoulders brand is good.

head and shoulders. it’s probably not dandruff, just dry scalp. Dandruff is bacteria build up, dry scalp just needs more conditioning and massage, try kerastase, the green line

Seborrhea is not just skin dryness. Actually, the word “seborrhea” means “too much oil.” Seborrhea is also known as seborrheic dermatitis or common dandruff.

Seborrhea can present as a variety of conditions such as dandruff, thick scales on the scalp, redness on the face or in the armpits, or raw, red patches below the *******. Although some of these conditions may feel “dry,” moisturizing only makes them redder. In other cases the skin may seem oily or even oily and dry at the same time.

Shampoos — Here are some ingredients in medicated shampoos that you can look for to help control seborrhea of the scalp. All are over-the-counter.

Tar
Salicylic acid
Zinc
Selenium sulfide
ketoconazole

Dandruff (also called scurf; its scientific name is Pityriasis capitis) is the excessive flaking of dead skin that forms on the scalp. As it is normal for skin cells to die and flake off, a small amount of flaking is normal and in fact quite common. Some people, however, either chronically or as a result of certain triggers, experience an unusually large amount of flaking, which can also be accompanied by redness and irritation. Most cases of dandruff can be treated with specialized shampoos or common household remedies.

Dandruff can also be a symptom of seborrheic dermatitis, psoriasis, fungal infection or head lice. Excessive scratching should be avoided. Scratching to the point of causing breaks in the skin can increase the risk for infections, particularly from staph and strep bacteria. While these infections are the biggest risk from dandruff, many people find that dandruff can cause social or self-esteem issues, so treatment can be very important for purely social reasons.

Causes

As skin grows, epidermal cells are pushed outward where they eventually die and flake off the head. In most people, these flakes of skin are too small to be visible. However, certain conditions cause cell turnover to be unusually rapid, especially common in the scalp. In people with dandruff, skin cells may die and be replaced about once every two weeks, as opposed to around once a month in people without dandruff. The result is that dead skin cells are shed in large clumps, which appear as small, white or grayish patches on the scalp.

Dandruff is believed to be the result of a combination of factors. Some of these factors are well studied, whereas others have not been thoroughly investigated.

The most common cause of dandruff is the fungus Malassezia furfur (previously known as Pityrosporum ovale). This fungus is found naturally on the skin surface of both healthy people and those with dandruff. The fungus metabolizes human fat, resulting in a lipid byproduct that is antigenic. Hence, the dermatitis in areas where sebum is found, areas with many sebaceous glands (on the scalp, face and upper part of the body). When Malassezia furfur grows too rapidly, the natural renewal of cells is disturbed and dandruff appears with itching. Other fungi may have a similar role in causing dandruff, as may certain bacteria.

Treatment

The appearance of flakes can be reduced, especially in those who suffer from only a mild case of dandruff, by proper hair care. Some people mistakenly avoid washing their hair, believing that the drying effect of shampoo will worsen their dandruff. By washing the hair regularly, however, dead skin is in fact removed before it can build up into larger, more noticeable flakes. Using acid-based shampoos helps restore acidity to the scalp, breaking down oils and preventing dead skin cells from collecting into visible clumps. However, shampoos with milder medication, or shampoos that are not marked to treat seborrheic dermatitis, may have little to no effect on redness and irritation.

Household remedies to get rid of dandruff are apple cider vinegar (the gold standard of household remedies), salt or lemon juice. Apply the liquid to the scalp and allow to remain for several minutes to several hours, even overnight, then shampoo and rinse clean in the shower. One good way to apply the liquid is from a spray bottle, or simply by pouring over the head. Apple cider vinegar can also be used as a rinse after shampooing: the vinegar will act as both a fungicide to fight the cause of the cell buildup, as well as a rinsing agent, which will rinse clumps of skin away before they appear large enough to be visible.

Severe forms of dandruff, particularly if accompanied by flaking or scaling on other parts of the body, should be treated by a dermatologist. Dandruff can occur in conjunction with skin conditions such as seborrheic dermatitis and psoriasis.

Dandruff varies from person to person. It may be necessary to try various shampoos with different active ingredients (selenium sulfide, tar, salicylic acid, zinc pyrithione, ketoconazole) to find the best suited for any one individual. Also, an individual may find that alternating between different treatments will be more effective than sticking with a single treatment, which can become less effective over time.

Tea tree oil’s antifungal activity has been found useful in the treatment of dandruff.

i don’t know what causes it… it could be weather change.. or many things.. now what to use… i have very bad dandruff so i use the product T-Gel.. but it stinks horribly bad so after i rinse it out i use my normal shampoo.. i use the T-Gel once maybe twice a week.. let is sit on your head like 3 minutes in the shower before rinsing.. you should be good

Dandruff is caused by the epidermal layer becoming overactive. Normally the scalp cycle is every 28 days, but if you are stressed or on medication, it can speed up, causing flaky itchy scalp.
Best bet is to use a low sodium shampoo like Redken or Nexxus for about 8 weeks until it settles. I don’t think dandruff is easily solved, but healthy diet and hair product is most important.
If you use the dandruff shampoos, and don’t get to the root of the problem first, it will just come back when you stop using it.

Well as I am going through this at this time I can only tell you my success at this moment. I have started washing my hair with Neutrogena®
extra strength T/Gel shampoo. I leave it in for as long as I can as the directions say. Then after I don’t put in a condition til I get out. Then I use Thermasilk Leave In conditioner and there Gel which bother are heat activated. So they both get a boost of conditioning with the heat. It isn’t easy when you start cuz the stuff smells nasty but it does work for me. But I do agree to the staying away from Head and Shoulders.

Hope this help ya
Vicki
