My basic hair care knowledge!
You see? Hair is pourus, with many scales. Under a microscope, you will see scales like a reptile. These scales are important for they lock in moisture and oil.
First, if you use very hot water for shampooing, it softens the hair strand and pries open the scales. Thus, oil and moisture is exposed to the elements and it dries out, causing static.
Hair is dead tissue... no matter how you look at it. Hair grows in the scalp. A cell is born and is alive, to be replaced by more cells. Thus hair grows, but each cell that is replaced by another dies and is held by protein bonds. So there is no way for hair to get any nurishment unless you add it. Thus protein (Keratin), Sebum (oil), and water...
Use luke warm water when washing and conditioning hair. Hotter water will pry open the scales. That means washing hair in a sink or turning the water to a luke warm position in the shower. Many women wash their hair seperately from bathing or showering. Luke warm water will keep prying to a minimum.
Mosture is a strange thing. There are a lot of moisturizing shampoos and conditioners, but the key ingredient is glycerin. This magic molecule adheres water molecules to the hair strand. There in most shampoos and conditioners is glycerin... Funny. Isn't it?
Protein. Keratin is the protein that makes up hair and nails...nails are just fused hairs together. (look at your nails and see many hairs cemented together.) You are looking for a Keratin, or Dehydrated Animal Protiein... and do not ask my where it comes from!! When you are driving and see something in the road... that's as far as you need to know about that substance. The Oil is Sebum. It makes hair oily. And, is what you want to do to get rid of acne..smae substance. Brush your hair 100 times before you go to bed... you are bringing the sebum down.
These are the things you need to keep your hair healthy. Wash hair in luke warm water. Use a gentle shampoo. All shampoos have detergent in them to undo the sticky bonds of gross out pollution and excess oil. Any other oils and proteins in shampoos will just wash away... so don't be foioled by expensive shampoos... Haircare product manufactures don't want you to know that. Luke warm water and mild shampoo. No all in one products! It just washes away... most of it.... and does not do a good job!
Conditioner is another story. You need the proteins and oils to revitalize your hair. Good conditioners are a must. Protein and oil will replenish what time, weather and washing take away.
