ما هو Does الشامبو Do?
You may think شعرك hair is dirty if you did not wash it لـ days, و yes, it does need some cleaning, but شعرك hair is not dirty as you think. That is unless you are purposely playing around في mud or having food fights with others where it lands في شعرك hair. The accurate way إلى describe شعرك hair that you have not washed لـ some time is that it is dull و greasy. That is because sebum is fatty substance that comes from glands في شعرك scalp, و you have it throughout شعرك skin.Too much sebum also can result في acne on شعرك face و can cause شعرك face إلى feel greasy same way as شعرك hair does if you do not wash it لـ days. However, you need sebum إلى keep شعرك skin protected as well as شعرك hair و hair follicles. Your hair has healthy shine when it is clean و في good health because من healthy levels من sebum.
That is because substance coats و protects outer keratin coating من every strand, which is why it has lovely shine.
However, if you do not wash شعرك hair very often, levels من sebum will become unbalanced, و that not only risks you developing acne, but it will cause شعرك hair إلى appear dirty.
Once sebum accumulates, that will cause hair strands إلى clump together, و that causes شعرك hair إلى appear greasy و dull. Additionally, pollen, dust, و other chemicals will attach themselves إلى sebum, و that is how you end up with "dirty" hair.
The one thing إلى know about sebum is that it is hydrophobic, which will make شعرك skin و hair waterproof.
Therefore, you can wash away dirt, dust, pollen, و other particles. However, you can never wash away oil و sebum regardless من how much water you use. That is why you need shampoo إلى do job.
الشامبو Can Work Its Magic
متى you are ready إلى wash شعرك clothes, you know that you do not end up with clean clothes if you do not use detergent.The same goes لـ شعرك skin which is why you need soap. Therefore, shampoo is essentially detergent. Whether it is laundry detergent or shampoo, detergents work as surfactant, which reduces surface tension من water. It helps stop it from sticking إلى itself و encourages it إلى bind with other particles, including oil. There is part من detergent molecule that is hydrophobic as that is hydrocarbon part.
That part من molecule is what causes oils و sebum إلى bind إلى it. That is في addition إلى any styling products that have oil في them.
The molecules في detergent also have hydrophilic part which means it responds very well إلى water. Therefore, when you wash شعرك hair, you are sweeping away shampoo. You are also removing sebum و other oils و dirt along with it. That is primary way how shampoo cleans شعرك hair. However, there are other ingredients في shampoo that deserve credit لـ doing their job too.
ما هو Ingredients In الشامبو Help Clean Your الشعر?
You don't want shampoo that only cleans شعرك hair. You want one that can wash شعرك hair و nourish it by promoting healthy appearance. That is why you have ingredients في شعرك shampoo that can do that. In addition, there are conditioning agents that will help replace protective coating after washing شعرك hair, add shine, smooth cuticle, و help detangle شعرك hair.Finally, shampoo contains fatty alcohols that will keep static و frizz at bay.
The shampoo also contains protectants such as sunscreen و heat protectants, which can help protect شعرك hair from sun و damage from heat. In addition, there are also chemical protectants في shampoo, which can help prevent chemical damage from treatments و swimming.
There are also functional ingredients that keep mix من shampoo healthy و can help prevent mold و bacteria from growing في it.
In addition, some preservatives can help increase shelf life. Finally, cosmetic ingredients do not affect how shampoo washes شعرك hair, but colorants و fragrances.
However, one type من shampoo would not work لـ specific kind من hair. There are also other ingredients في shampoo designed لـ colored hair, dry hair, oily hair, و normal hair. Many shampoos can include sulfates which can dry hair, و if you have dry or colored hair, you will want إلى avoid shampoo with sulfates.
Therefore, all shampoos work same way, but not all من them are same as they should not be.
Does Lathering Up Clean Your الشعر More?
Many shampoos contain ingredients that cause lathering, but lathering في itself is not going إلى help clean شعرك hair في any way at all. Many shampoos have lathering agents because consumers like them, و it has nothing إلى do with improving shampoo.Therefore, if you like lather, you will want إلى go لـ shampoo that provides good lather because it has plenty من agents that cause it.
