To understand the biology and science of the growing hair, it is important to first know that the hair cells continuously reproduce. The biological site for this growth is the dermal papillae. Dermal means cuticle, skin, covering, or epidermal, and papillae mean outgrowth or processes. We might also call this site the follicle.

When these growth sites are destroyed or damage from second degree burns for instance, the dermal papillae makeup is changed. It does not necessarily mean that the biological growth site will stop producing. Our bodies have the ability to regenerate and repair cells. The damaged dermal papillae will produce again once regeneration is complete and the skin is normal again.

New growth may look different than the original and is often sparse and may be fuzzy and thinner than the original. For example, when people undergo chemotherapy the treatment destroys good cells with the bad and causes hair loss. Even though this is not a trauma to the skin, there are some changes in regrowth. Transplantation will also cause irregular growth.

New growth does not erupt from the skin one strand at a time. Rather, it comes up from the scalp in a grouping of more than three strands. The speed at which it grows is estimated to be about a half inch each month. For a healthier scalp the growth time may be less, while others may have slower growth time.

Every five months our hairs naturally sheds and is replaced by new strands that are healthy and strong. Under normal conditions, old shafts are pushed out and replaced by the new strands. However in situations such as male pattern baldness, once the loss occurs it is not replaced. Scientists are investigating this phenomenon to see if there is a way to stimulate new growth.

At present, the two main ways to treat baldness is to cover it up, restore it by transplant, or use medications. There are some changes coming since science has proven that certain minerals and vitamins are needed for the follicles to be healthy to promote growth. The correct mixture of vitamins, minerals, and supplements the contain sulfur, are necessary to promote healthy hair growth. It should be kept in mind that these treatments have their limitations and no one treatment works well for everyone.

Treatment options are likely to improve with universities and private laboratories searching for a valid remedy for the problem. The two approaches that are likely to succeed are cloning and gene therapy. Key genes in the follicles have already been identified that cause dysfunctional growth when they mutate. There are a number of diseases that cause baldness that involve some sort of genetic phenomenon. Biologists are focused on correcting the genetic errors that cause the problem. Cloning is the process of growing new follicles from stem cells. These cells are collected from a donor and supported in a lab until they multiply.

Considering the improvements made in the biology and science of growing hair, it is reasonable to expect to see these approaches successfully used to treat hair loss. At one time people considered the condition part of life that had to be accepted, today there is hope for a cure.
