Well, nobody knows your hair better than you do and there can be benefits to both shampooing your hair every day and doing it less frequently. Daily lathering up won’t do your hair any harm if you do any of the following:
You exercise that makes your scalp very sweaty
You use gels or waxes to set your hair
You use hair sprays and other styling products that come in contact with your scalp
You naturally have an oily scalp
Shampooing Everyday is Good When…
Your Scalp is oily
We can see you yelling (me, me!) already. Contrary to all the wisdom you read in umpteen beauty magazines, washing an oily scalp daily is not bad. Just do it with a mild shampoo, which has the correct pH.
If you do want to attempt to go more than a couple days without shampooing your hair, try a dry shampoo. They are formulated to soak up oils, buying you a day or two between shampoos.
You Use Hair Cosmetics
If you use gels, waxes, hair serums, hair sprays or other hair styling products, you should always wash your hair before going to bed. If you will sleep with these cosmetics on, they might rub into your scalp as you sleep and block your skin pores.
Most of these styling products are made with mildly toxic products that cannot be ingested. And allowing them to enter your bloodstream through your skin is same as eating them.
If you cannot avoid using many hair styling cosmetics, the best you can do to save your hair is to wash it before going to bed.
You Sweat a Lot
Sweat contains lactic acid, which if left on the scalp, can cause hair fall in some people. Not just this, sweat also contains Dihydrotestosterone or DHT, which is a hormone that restricts blood flow to the hair follicles, in effect restricting nutrient supply to the hair, starving it to death. So, washing it daily to get rid of the sweat could help.
Your Scalp Produces Too Much Sebum
If your scalp and hair gets greasy during the course of one day, consider washing it well once a day to help keep your scalp pores clear. Your scalp sebum is the natural oil secreted from your skin also contains DHT, which as we told you earlier, can cause hair loss.
It is advisable to keep scalp sebum to a minimum especially for people who are already experiencing hair loss. If your scalp creates excessive sebum, it could indicate that your liver does not contain sufficient co-enzyme A levels or that it isn’t optimally functioning. You could get your liver tested too.
Frequent Shampooing can Cause Problems If…
Washing your hair often can rip off your skin sebum which acts as a natural conditioner for your hair and makes it shiny. Frequent washing can make your hair dry, resulting in unhealthy looking tresses.
Also, stay away from cheap shampoos, or the ones with harsh chemicals such as sodium lauryl sulphate (SLS). Switch to a shampoo that doesn’t contain SLS and concentrate on washing the roots because it’s your scalp that’s oily.
Here is a useful tip for people who choose to wash their hair daily- Apply conditioner first only to the bottom third of hair (if you have oily hair, don’t use conditioner on the roots, it will weigh hair down). Keeping the conditioner in, apply shampoo to the roots and lather up. Rinse everything off. Your roots will be lifted, but the rest of your hair will retain its shine.
