Dirty hair is my favorite hair because it shows me that you are taking care of your hair. I know, I know that sounds like the exact opposite of what you would expect! But everything your body does is for a reason, and the oils
your scalp produces are made for your hair. The sebum (oil produced by the sebaceous glands on your scalp) protect and moisturize your hair strand and scalp, so shampooing too frequently strips the hair of this.
Let’s get down to the science of it. When your hair is in water, the ph of water is 7 and the ph of hair is 4.5-5.5. Water raises the cuticle of your hair, and when shampoo, which is a surfactant, is added, the oil clings to the water. Cheaper shampoos use harsh sulfates that are chemically based, while more natural products are coconut based. This is why your shampoo is extremely important.
I suggest shampooing every 3 days. However, keep in mind that it also depends on your hair texture. Curlier hair types always need more conditioning and moisture. The more texture you have the longer you can go without shampoo.If you shampoo your hair every day and stip it of its needed oils, your scalp will start to produce more oils to compensate. You have to train your scalp to stop producing as many oils. The key to this is being patient. You will start with oily hair but over time that will decrease. The best way to start that process is to try rinsing and conditioning every day.; it gives you the satisfaction of washing your hair without stripping the oils. From here, you can eventually start washing every two days.
As this process goes on you will create healthier hair; your heat styles will last longer and so will your color. It is a great way to save your hair and your time.
