Rub long enough for the shampoo to cover the scalp. When washing your hair, it’s not how long you rub the shampoo in, but how well you rub it. The exact time may vary, depending on the thickness and dirtiness of the hair. The main thing is that you have to focus on rubbing the shampoo into the entire scalp from front to back. ^{[1] X Trusted Source PubMed Central Go to source} This will help you to have clean, elastic and healthy hair.

Some shampoos may instruct you to leave the shampoo on for a few minutes before rinsing it out. If you’re not sure, follow the directions on the shampoo bottle.

The scalp may become irritated. Most shampoos are not left on the hair. You must rinse the shampoo in the shower immediately after applying it to the lather. If you intend to leave the shampoo in your hair longer to get a clean feeling, please don’t – shampoos contain parabens, miranp and other ingredients that can cause contact dermatitis (red, itchy rash). Such a bad reaction is more likely to happen if the shampoo has more time in contact with the skin. ^{[2] X Trusted Source PubMed Central Go to Source}

How long should you leave your anti-dandruff shampoo on?

Leave for at least 5 minutes. Unlike regular shampoos, anti-dandruff shampoos need to be left on the scalp for enough time to work. After massaging the shampoo into your scalp (avoid rubbing the hair shaft as anti-dandruff shampoo dries out your hair), you should wait at least 5 minutes before rinsing the shampoo out. ^{[3] X Research Sources}

Experts recommend washing with a regular shampoo after using an anti-dandruff shampoo.
Pro tip: If you have dry hair, massage coconut oil into your hair 30 minutes before using an anti-dandruff shampoo. Coconut oil will lock moisture in the hair and prevent the hair from drying out due to dandruff shampoo.

How to properly wash your hair?

Focus on cleaning the scalp instead of the hair shaft. Shampoo is actually meant to be rubbed into the scalp, not the hair. Rubbing shampoo directly on the hair will only make the hair frizzy and tangled, completely not good for the hair. Instead, you should just massage a small amount of shampoo into the scalp underneath the hair and work around the entire scalp, then rinse off the lather. ^{[4] X Trusted Source PubMed Central Go to Source}

Rubbing and scratching your scalp may feel good, but don’t do it! Always be gentle when washing your hair so as not to damage or tangle your hair.
You don’t need to use a lot of shampoo to clean your hair. A small amount of shampoo the size of a grape is enough! ^{[5] X Research Sources}

Do not rinse and then wash again. Perhaps you have also read on the shampoo bottle that the instructions “flush and then wash again”. Luckily for your wallet (and busy mornings, too), you don’t need to wash it twice. These guides are often just promotional tips to get people to use and buy more. ^{[6] X Trusted Source Harvard Medical Schop Go to Source} One thorough shampooing is enough.

Always use conditioner after washing. When you use shampoo, you also take away the natural oils that condition your hair. For healthy and smooth hair, this oil needs to be replenished. That’s when you need conditioner. ^{[7] X Trusted Source PubMed Central Go to the source} Conditioner reduces static, increases shine and strengthens hair, so it’s a necessary step when washing your hair. ^{[8] X Trusted Source American Academy of Dermatpogy Go to Source}

Concentrate on massaging the conditioner into the ends of your hair. The ends of your hair are often the driest, and if you apply conditioner to the roots near the scalp, your hair will feel heavy.

How often should you wash your hair?

This depends on the hair type. Everyone’s hair is different. Daily shampooing may be suitable for some people, for others 1-2 times should be fine. In general, the thickness of your hair and the amount of oil your scalp produces are the factors that determine how often you wash your hair. Here are some general guidelines that you can refer to: ^{[9] X Research Sources}

For fine, thin or oily hair: Wash every other day or every other day.
For medium thick or dry hair: Wash your hair every 2-3 days.
For thick or curly hair: Wash your hair once every 1-2 weeks.

This also depends on your lifestyle. Your hair will get dirty faster if you exercise and sweat a lot. If you use a lot of products on your hair, your hair will also get greasy faster than when you don’t use it. Living in a highly polluted area can also cause your hair to get dirty faster. ^{[10] X Research Source} All of this means you need to wash your hair more often. While hair type is important, you can try washing your hair at different frequencies to see what works for your lifestyle.

You may have heard that washing your hair less often makes your scalp less oily, but that’s just a myth! Oil production is controlled by hormones, not by how much or how little you wash your hair. ^{[11] X Cleveland Clinic Trusted Source Go to Source}
