(Video) Is It Dandruff Or A Dry Scalp? Here's What You Need To Know
You may find it difficult to tell the difference between dandruff and dry scalp as both can present themselves in a similar way. Both can cause flaking and itchy scalp.
But while dandruff is related to seborrheic dermatitis, a dry scalp is simplyrelatedyour skin losing a lot of water. This can happen when you aren't getting enough fluids.
But it could also be caused by some hair products you might be using on your scalp that could be stripping your scalp of its natural oils. If you live in a cold, dry climate, you may also be more susceptible to dry scalp.
Treating a dry scalp usually involves switching to a mild, non-medicinal shampoo that contains as few additives as possible that can strip moisture from the scalp.
Here are some tips on things you can do to prevent dandruff:
- Practice good hygiene.Do your best to resist the urge to touch your scalp, especially if it's already itchy. Scratching can increase irritation and lead to a vicious cycle. When you pick and scratch it, you can also introduce dirt into the mix that can make your dandruff worse.
- Find the right shampoo balance for your scalp.Wash often enough to avoid greasiness, but don't use too many products on your hair as they can irritate your scalp.
- Reduce stress.Stress can aggravate or even make dandruff worse in some people. While stress doesn't introduce Malassezia to the scalp, it can thrive if your immune system is compromised, which is exactly what stress does to your body. Do your scalp a favor and relax. Try taking an invigorating walk or practicing yoga. You may even find it helpful to keep track of stressful events. Write down what they are and how they affect your dandruff. That way, you can do everything you can to avoid potential triggers in the future.
- Breathe fresh hair.Investigationshowsthat including regular exposure to the outdoors, especially where the air is cooler, can help reduce oil buildup on the scalp.
- Massage the scalp.This can also help prevent dandruff symptoms.
- Brush those strands.Brush your hair when it's damp (not wet) at least twice a day.
- Limit friction.Limit the use of hats and scarves, especially those made of synthetic materials.
The good news is that many cases of dandruff can be effectively treated with over-the-counter (OTC) shampoos and other lifestyle measures.
That said, dandruff isn't the only reason you might have itchy scalp. If your dandruff is particularly persistent or itchy, you may have psoriasis, eczema, or a true yeast infection. Your doctor can help.
If the itching doesn't subside or your scalp becomes red or swollen, talk to your doctor. Also monitor if shampoos don't help, if redness and scaling spreads to your face or other areas of your body, or if itching starts to interfere with your daily life.
Sometimes symptoms canindicateother more serious conditions such as actinic keratosis (AK) or tinea capitis (tinea capitis), and it is best to check the best treatment.
Q: When should I see a dandruff specialist? What kind of specialist treats you?
A: Consider talking to a dermatologist if your scalp flakiness persists even after consistently following the recommended habits below and using over-the-counter remedies.
