Anatomy of Hair
Hair actually spans throughout your three layers of skin: the epidermis, dermis and hypodermis. What we normally call the “root” of hair is in the deep layer of the hypodermis. The root (formally called the papilla) looks a lot like a little ball of fibers. It sits right above a blood vessel which provides the papilla with nutrients so it can make new hair cells.
As the papilla makes new hair cells, they grow outwards. The central shaft of a hair is called the medulla. It is what reflects light and gives hairs their lustrous colors. The middle layer of hair is called the cortex. Its shape will determine the texture of your hair, like straight or curly. The cortex also determines the color of your hair because it contains melanin. The outermost part of the hair is called the cuticle and its job is to protect the hair from damage. As your hair extends outwards and finally out of the body, it becomes thinner.
The Phases of Hair Growth
The average Caucasian person has about 5 million hairs on their head alone. At any given moment, these hairs are in one of 3 different stages of hair growth.
- Anagen phase: The anagen phase is when your hair is actually growing and lasts for about 2-8 years. During this phase, the papilla (root) of your hair is getting nutrients from a blood vessel. The papilla quickly makes new hair cells which build upwards into the parts of your hair.
- Catagen phase: After being in anagen phase, a hair follicle will start to deteriorate and get much thinner. The root gets separated from its blood supply so the hair can no longer grow. The root will disintegrate and the strand of hair will get pushed upwards but not fall out.
- Telogen phase: At any given moment, about 10-15% of your hairs are in the telogen phase. During this phase, the hair is dormant in the follicle and does not grow. It is essentially resting until it goes back into the anagen phase about 2-4 months later. When the follicle goes back into anagen phase, the newly grown hair will push out the old dormant hair from the telogen phase. The goal of Ultra Hair Away is to get all your hairs permanently into the telogen phase.
Ultra Hair Away Mechanism of Action
Ultra Hair Away uses enzymes and various chemicals to directly impact the hair root (papilla) so it can no longer produce new cells. For Ultra Hair Away to work, you first must be able to access your hair root. So, you will need to first remove your hair, preferably by waxing or tweezing as this will remove the entire length of the hair, not just the external parts like shaving does. Your hair follicle will be empty down to the papilla so Ultra Hair Away can enter and get to work.
The ingredients in Ultra Hair Away will block your papilla. The first time you apply Ultra Hair Away, it will inhibit the papilla’s ability to make new cells so your hair grows much slower and becomes thinner. As you continue to apply Ultra Hair Away, your hair gets separated from the blood vessel which feeds it. When this happens, the hair follicle is prematurely pushed into the telogen phase, i.e. the resting phase.
The goal of Ultra Hair Away is to keep your follicle in the telogen phase. Because Ultra Hair Away blocks the follicle root, a new papilla will not be able to form. Your follicle then stays in this resting period so you will not grow hair there again.
