Improvements in hair transplants come every decade or so, but perhaps it is not wrong to expect more advancement in hair science and hair transplant technologies. We all wait for that magical solution to hair loss.
The current situation is like this: hair transplant operation is the only permanent solution for male pattern hair loss. There are some medications that work for different types of hair loss or scalp diseases, and yet, the hereditary balding can be treated only by medical surgery. There are mainly two techniques available: The Follicular Unit Extraction (FUE) and Follicular Unit Transplantation (FUT). The advanced form of FUE is newer than FUT, and has proved to be an effective way to treat male pattern baldness. However, there are also cases, patterns where FUT can be more suitable.
For now, it looks like FUE is more successful than FUT. It will remain so for a while.
In the meanwhile, the pharmaceutical industry is working on new drugs for treating certain types of hair loss (alopecia). The cosmetic industry is also advancing: there will soon be more durable and more natural looking wigs and hairpieces available.
The next big thing will probably be hair “cloning”. The more realistic term should perhaps be hair multiplication. The hair follicles are extracted from the scalp in hair multiplication as in hair transplant operations, and they are multiplied, and then re-implanted into the scalp. This procedure is still under debate and research. It is uncertain when it will be available because the current research is not sufficient to prove that this procedure is efficient for hair loss.
If entirely tested, and proves to be effective and efficient, hair cloning/multiplication will allow for providing an unlimited source of hair follicles to transplant. Otherwise, hair care products and hair transplant surgeries are improving. We might see more products such as concealer sprays that cover the scalp, and give a natural look. As for hair cloning, we need to wait a bit longer. How long? Nobody knows. Hopefully, the researchers will overcome the obstacles, and hair multiplication will be possible soon.
