Usually 6 weeks is early to expect results from Minoxidil 5%, two times a day? For hair loss in the scalp and beard.

Thank you for your question. I do believe that using Platelet Rich Plasma injection can speed up the trichostimulatory process around the scar tissue. If the scar tissue is visible in the frontal area it’s worth considering an early PRP series. Sincerely Dr. Shanthala

Your questions is troubling because steroid injections do not usually grow beard hair (or any hair).  There are side effects associated with steroid injections (as with any medications).  However, stretch marks is not usually one of them.  

Genetic androgenic alopecia can start with puberty so you may be seeing early signs.  You need to see a doctor for an exam if you want a diagnosis.  There is no way to completely stop genetic hair loss.

It is difficult at times for patients when they do not see results.  Sometimes this may mean that the drug is not working for you.  It does not work on everybody.  Taking a higher dose may not be the answer.  In fact you may have side effects.  

You generally cannot "stop" genetic hair loss.  There are medical and surgical treatment options but these are not "cures".  You first need to see a doctor for an exam and establish a treatment plan.

Minoxidil 5% is what is recommended for treating hair loss.  Higher strength does not always mean better results.  Higher strength can actually have greater risk of side effects.  No studies show azelaic acid works for hair loss.
