There is this doctor called Dr Nigam who claims:
1. He can regenerate donor hair 3 different ways...
-1A. In Vivo Doubling: Somewhat similar to what Gho claims. The hair is "split" in the scalp, and the bisected follicle is implanted in the recipient area. If it works, hair grows in recipient area and grows back in donor area.
-1B. In Vitro Doubling: Similar to above, but in this case the entire follicle is extracted, then bisected in vitro. One part is put back in the donor area, the other part is placed back in the recipient. This method yields close to 100% regeneration, according to Dr. Nigam.
-1C. De Novo Doubling: Similar to above, but both halves are placed in the recipient area, and the donor hair is regenerated using ECM/Patient's previously cultured Stem Cells/(maybe PRP?)/Etc.
2. He also claims he can multiply hair non-surgically (like Aderans and Intercytex et al were/are trying to do) using the patient's own cultured adult stem cells.
Among other things that transpired during the visit: Dr. Mwamba performed a typical FUE on one of Dr. Nigam's patients, and Dr. Nigam used his stem cell treatment from 1C in an attempt to regenerate the donor hair.
