What is hair?

Hair is actually made of 90 percent of protein. There is the root, the shaft and the follicle, and actually the shaft is made of keratin. The cuticle part of the hair protects your hair shaft.

How does hair grow?

Hair grows from the base of your scalp through the follicle. It depends on your nutrition, your health, everything affects the look of your hair. Hair processing, perms, hair coloring, anything that goes onto your hair affects the health of your hair.

What is the hair cuticle?

The hair cuticle is the outer coating of the hair, and the hair cuticle also gives the look of the hair. If you have frizzy hair, flyaway hair, usually the hair cuticle is damaged. Therefore, you want something that's going to smooth it out, make it look shiny. That's where hair products like hair serums, silicone products, and oils come into play. They coat the outer shaft of the hair, and they give that beautiful, shiny texture.

What is the hair medulla?

The hair medulla is actually a group of cells that make up the chemical composition of the hair. Usually, people with coarser hair have more medulla whereas people with finer hair, flatter textured hair, they usually have less medulla in their hair.

What is the typical life cycle for hair?

The typical life cycle for hair would be approximately two to seven years. This all depends on your health; your nutrition; how you take care of your hair. How you blow dry it actually is very normal to lose a hundred hairs a day. It sounds like a lot, but it's a very normal process. When the hair falls out, you will have it automatically grow out again. That's why you'll see on a lot of people they will have small little hairs around the hair line. And I always tell them, "That's a great thing! That's a good thing!" It means your hair is growing. It's growing back again. And it's growing back healthy.
