  • How to shampoo our hair?

    Posted by Abdullah on October 13, 2021 at 4:23 am

    Some people say we should shampoo and lather on scalp because dirt and oil is on scalp and not the hair and at the end we can move the lather to the rest of hair and wash it.

    Some people say we should shampoo and lather the hair and not scalp because the conditioning ingredients should deposit in hair not on scalp. If conditioning ingredients deposit on scalp it can irritate the scalp and scalp feel oily very soon. 

    So what is the better way to shampoo our hair especially for women and with conditioning shampoo (silicone+polymer)?

    I think the way that people with longer hair use these products, and which products they choose, depends on all sorts of variables such as hair type, hair length, hair condition and regularity of washing. I will tell you how I use hair cleansing products, but other people’s routines may be very different.

    I am a female in my mid-20’s with medium length (about armpit length) European hair which is naturally fine (but appears thick because I have a lot of it), relatively straight, and naturally light brown in colour. It was bleached about 2 years ago, so the ends are more porous and lack lipids, though there has not been repeated damage from multiple treatments.

    When I shampoo my hair, my main aim is to remove oils from the hair closest to the scalp and the scalp surface, so I will focus on the scalp area, lather, and then pull the lather down the length of my hair to lightly shampoo the lengths. I wouldn’t expect silicones and polymers to be in a high concentration in a shampoo product as I would only expect mild conditioning and will use a conditioner product to add more conditioning to the parts of my hair that need it most.

    A 2-in-1 shampoo and conditioner formulation has always left too much deposit at the roots, and not enough conditioning on the lengths of my hair, so I always use a separate conditioner product and avoid 2-in-1 products.

    When I apply the conditioner, I will apply it to the lengths only (roughly below my ears) as that section of hair has been exposed to more aggressors, and too much deposition at the root will weigh down the roots and appear greasy. I will leave it for a couple of minutes before rinsing.

    On the rare occasion that I swim, I will “co-wash” afterwards, which means I use conditioner at the roots and through the lengths (and skip shampoo) because the cationic surfactants will still provide some mild cleansing but the heavy conditioning helps to hide chlorine damage.

    Hopefully that is of some help.

    European descent female here, with long fine hair (past my waistline) that I keep up most of the time (working in a lab, sort of necessary). When I shampoo I focus on my scalp and only then work the lather into the hair before rinsing, and I don’t let it stay on the hair for long.

    When I condition, which is 2-3 times a week following shampooing, I will usually use a leave-in and start at the ends, working it up but not all the way to the scalp. I have never bleached my hair, but I do use henna on occasion. I also haven’t had my hair cut in over two years now, but am having very little trouble with splint ends and tangling due to using the leave-ins with either silicones or castor oil.

    thanks @CedarS 
    Does your shampoo have cationic polymer or silicone? 

    If yes which one?

    So the shampoo I use most often has dimethicone in it. The other shampoo is a clarifying shampoo I use every other week or so, and it has neither in it.
