It usually takes 6+ months to see results after starting Minoxidil 5%. Some may see early results but that is rare. Sometimes it actually takes longer than 6 months to see results.
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.

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.
