Dandruff: FAQ
How do I know if it's dandruff?
Dandruff is an extremely common condition with well-known symptoms. While there are skin problems such as seborrheic dermatitis or scalp psoriasis that can mimic the symptoms of dandruff, these conditions are far less common than dandruff. If you have flakes that are visible on your scalp, and it is not too severe, it is very likely that you have dandruff. If redness, severe itching, or silvery scales accompany the flakes, or the condition cannot be controlled with medicated shampoos, we suggest that you visit a dermatologist so that they can make a proper diagnosis.
I've started using dandruff shampoos, but in the meantime, how do I hide my dandruff?
It's very easy to become self-conscious if you have dandruff, but for the most part, others don't notice anything. If you are still concerned, try to wear white or lighter color clothing, as they hide dandruff flakes well. If you have a black t-shirt or sweater, the flakes can be visible around the shoulders.
My dandruff goes away after using dandruff shampoos, but it keeps coming back. What can I do?
Dandruff will often be a chronic condition that recurs from time to time. Unfortunately, some people are susceptible to this condition. Dandruff can be controlled and maintained relatively easily with dandruff shampoos. If you do not notice improvement within 2 weeks, or a worsening of the condition, visit your doctor for a proper diagnosis as it may be another problem.
Which dandruff shampoos should I use?
Most known brand names should have shampoos that contain one or more of the following active ingredients: Salicylic Acid, Selenium Sulfide, Ketaconazole, Sulfur, Coal Tar, and Zinc Pyrithione. Each tackle the dandruff problem in different ways, and you may need to find out via trial and error, which products work the best for your hair.
How long does it typically take for dandruff shampoos to work?
Generally, dandruff shampoos that can be bought over the counter should clear out most cases of dandruff within 2 weeks. Even if it does not remove the dandruff completely, significant improvement should be seen.
My baby seems to have severe dandruff. Is this possible?
Yes, it is called cradle cap, and is a very common condition in infants. It is not dandruff, but related to a condition called seborrheic dermatitis that occurs in new born babies. Unless the cradle cap is extremely severe, gentle washing is all that is necessary, as it tends to clear on its own. Oils or lotions may help break down the scales. If the condition persists or worsens, visit a paediatrician, as it may be a fungal infection.
I have dandruff, but recently my scalp itches. Is this normal?
Itching and minor irritation are normal symptoms of dandruff. If you treat your hair with dandruff shampoos, you should be able to clear your dandruff, which should eliminate the itching on your scalp.
How do I know that I don't have seborrheic dermatitis or scalp psoriasis?
