Dandruff is a condition that affects the scalp. It occurs when the scalp produces and sheds skin cells at an abnormally fast rate. This results in dry, flaky skin that appears in small white flakes or patches.
Many people think that just washing their hair will remove dandruff, but in reality, many people still have dandruff after washing their hair. There are several main reasons why dandruff still appears on the head even after washing the hair many times.
There are many reasons why dandruff still appears after washing your hair.
Wash your hair with hot water
Washing your hair with water that is too hot is the cause of dandruff because the scalp is dry, creating white dandruff flakes on the hair. In addition, when washing with hot water, hair is easily dry and brittle, increasing the condition of hair breakage and loss. You should wash your hair with warm water, this will reduce dandruff quickly.
Scratching the scalp too hard when washing
The habit of scratching vigorously when washing your hair is not only harmful to the hair roots but also bad for the scalp. The act of scratching vigorously makes the skin structure easily peeled and damaged. This is also the cause of dandruff even after washing your hair. It is best to gently massage your scalp when washing, helping to effectively limit the condition of brittle and falling hair.
Hair rinse not clean
Not rinsing your hair thoroughly after washing will cause the shampoo foam to remain on your ears or the back of your neck. Therefore, you should pay attention to rinsing your entire head thoroughly with water to avoid leaving any shampoo foam that will cause itching or scalp fungus.
Not rinsing hair properly is also a cause of dandruff.
Change shampoo frequently
The hair cleanser you are using can cause dandruff to appear after washing. Constantly changing shampoos can irritate the scalp, leading to flaking and dandruff. You should choose a shampoo that suits your hair type so you don't have to change it too often. To clean your hair safely, you can also use natural ingredients such as grapefruit peel, soapberry or tea leaves.
Drying hair incorrectly
The cause of dry scalp is often drying hair too hot or drying for too long, causing the scalp to peel, creating dandruff, causing itchy scalp. After drying too hot, hair appears a lot of dandruff. To overcome this situation, adjust the temperature of the dryer, prioritize drying at low temperature. If not necessary, do not dry your hair for too long and it is best to let your hair dry naturally.
Go to bed wet
If you are wondering why you still have dandruff after washing your hair, the reason may be because you lie on your pillow and sleep with your hair still wet. This will make your hair more prone to breakage and dandruff, even scalp fungus. Therefore, you should dry your hair completely before going to bed.
Washing your hair too often
Many people with dandruff think that washing their hair regularly will help get rid of dandruff. However, in reality, it only helps the scalp to be "instantly" clean, reducing itching and discomfort. However, washing your hair alone cannot cure dandruff at its root, nor can it completely cure the cause of dandruff. On the contrary, washing your hair too often causes the scalp to lose its natural oils to nourish the scalp, making it easier for fungus and dandruff to grow.
Note to avoid dandruff on the scalp
- Get into the habit of washing your hair early in the morning, avoid washing your hair at night. After washing your hair, you should only dry the roots at low temperature.
- The ideal frequency for shampooing is every 2 days. If you still feel itchy or your hair is sticky, you should not shampoo your hair continuously just to temporarily relieve the itch.
- You should choose and use special shampoos, shampoos specifically for each hair type to remove fungus and prevent dandruff from coming back. Special anti-dandruff shampoo is a very reasonable choice for those who need to completely remove dandruff, helping you regain a comfortable, refreshing feeling for your scalp.
- Change the habit of scratching your scalp vigorously when washing your hair. You should use your fingertips to gently massage in a circular motion around your scalp throughout the hair cleaning process.
- When using conditioner, apply conditioner at least 2 cm away from the hair roots. Rinse hair with cool water, you should tilt your head slightly, rinse from the hair roots to the ends to avoid the conditioner from entering the scalp with the water. Immediately after shampooing, you need to wipe and dry your hair.
In addition, you should regularly clean personal items that often come into contact with the scalp such as hats, helmets, towels, etc. to limit the growth of fungi and bacteria.
