Thank you for your question!
Hairloss at a young age such as yourself has multiple causes. It is important to have a proper consultation to exclude underlying medical, nutritional or physiological causes for hairloss prior to embarking on treatment. This is especially important as many of the treatments suggested for Male Pattern Hairloss can be costly, time-consuming and have a number of side-effects, and may not be required.
Once excluded, and it is determined that Male Pattern Balding (MPB) is the cause of the hairloss, then the various treatments as previous elucidated by the previous doctors can be considered. To answer your question on PRP - the national skin centre has recently concluded a study on PRP scalp injections in conjunction with minoxidil for the treatment of MPB. Preliminary results are quite encouraging.
Similarly, PRP scalp injections are used widely as adjunctive treatment in the Unger Clinic in the US, where Dr Martin Unger, a board-certified plastic surgeon who is world-renown for his work on hairloss, practices.
In Singapore, PRP injections for MPB can only be performed as part of an IRB-approved trial led by a Principle Investigator who is either a Plastic Surgeon or a Dermatologist.
Personally, I favour FUE hair transplantations for treatment of MPB. This allows for a definitive method of shifting hormone-resistent follicles from hair-dense areas of the scalp to the thinning areas. The results are permanent and long-lasting.
Thank you and best regards,
Dr Samuel Ho
