Presently there are three major firms that are leading the research into hair cloning:

Intercytex

The company closed in the end of 2009 and sold most of it's assets to ARI.

Intercytex was a major UK based Company that researched how to develop stem cells related products. It was also a major fundraiser for hair cloning research.

ICX-TRC is the company's most anticipated product which was hoped to become the 'permanent solution to hair loss'.

 

The idea of ICX-TRC takes the basics of hair cloning techniques where it will make use of the multiplied dermal papilla cells in order to help stimulate the formation of new hair follicles as well as triggering weakened follicles to grow again. This is done via injecting the cells directly into your scalp at specific locations where the stimulation will take place.

Aderans Research Institute

Aderans Research Institute (ARI) is a company based in Atlanta and Philadelphia. It function as a branch of the BOSLEY Group which is one of the major hair transplant network in the United States. ARI research team is lead by Dr. Washenik and Dr. Stenn, both very well recognized within the field of hair biology and hair restoration.

ARI is currently performing phase II trials of their technique which called 'follicular neogenesis'.This method involves the growing of dermal papilla cells and combining them in culture dishes with Keratinocytes.

ARI is considered the leading company in the research for hair cloning technology.

 

Follica Bio Labs

Follica is an American company that works under a worldwide license for their technology from the University of Pennsylvania. for developing a new hair cloning technology which is able to provide stimulation for the formation of new hair follicles.

The company is researching a fascinating new approach. The discovery was made by the company's founder, Dr. George Cotsarelis. He found that following a cut to the skin, it is possible to alter the repair cells to perform other tasks in addition to healing the cut, such as the triggering the formation of new hair follicles.

It is a complicated process which by applying a complex protein network known as WNT to small cuts to the skin, new hair begin to sprout out from an area where there was no hair previously.

Histogen Labs

Histogen is a new company that was established in 2007 and seems to have the best chance to be the first to release a preliminary hair cloning product into the market.

The company's flagship product is called Regenica. It is Under the supervision of Dr. Craig Ziering, a top hair transplant surgeon. The product comes as a proprietary liquid that utilizes newborn fibroblast cells which are cultivated in their self made embryonic chamber. After which harvesting the cell's secretion of embryonic proteins with bio factors and growth factors.

Studies have pointed to the fact that when applied onto the skin, these embryonic cells trigger the formation of new hair follicles. But there's more good news, as it also pointed to an increase in diameter (thickness) in existing hairs as well as increasing the amount of hairs growing out from the base of each hair follicle.

At the moment the company focus on obtaining more human safety data in order to allow for further human trials prior launching the product into the market.
