Because many stem cells are being grown in the lab from a few hairs, you will be able to grow many times the number of hairs removed.  This will end the limits of how much hair can be transplanted due to the limited amount of hair that can be extracted from the back of the scalp during normal hair transplants.

• A study is underway in Canada at the University of Toronto to develop hair culturing.
• A Dr. Gho in the Netherlands has been granted a European Patent as of 9/14/98 and is conducting a study on actual patients.  They expect their study to be done in 8 months (early 2000), after which time they plan to license the technology if it proves successful.
• Dr. Colin Jahoda of the UK is researching the process.
• At least one doctor in the US is seeking to develop the technique privately as well.

• Unlimited or nearly unlimited hairs to implant/transplant.
• Less scarring where hair is removed since less needs to be taken.
• Stem cells may be implanted by syringe which may mean less trauma to the implant area than traditional transplants.
• Less invasive procedure may require less anesthetic and involve less pain to the patient.
• Recent research indicates it may be possible to take donor cells from other individuals.

• Costs may be dramatically higher than traditional transplants, especially when the technique first becomes available.
• Cultured cells often have shorter lifespans than normal cells and it is possible that the hairs will not last a lifetime (and since the procedure is so new there will be no way to tell until it has been available a while).
• Implanting stem cells in this fashion can carry a risk of tumor or cyst formation - it is unclear at this point whether this may be a stumbling block to development.
