Why hair products don't affect your hair the way it should
Hint: Because it wasn't made for you.
Wait. Don't get angry on the companies that create it or me; they don't have a choice.
Let me explain: Your hair is affected by so many things, the climate, the water in your area, your ancestor's genes, and much more. When a company creates a new product, they are thinking about the most common hair type, so the largest group of clients could enjoy their products abilities.
But, some companies think about smaller groups. Let's take Miller Professional Care; for example, they created a line of products, made for the Israeli hair.
If you check their site, you can see that their message is built around that.
So, don't give up so fast on products, try to find the manufacturer who is creating products for you.
