Been following this thread with interest for few weeks so thought I'd jump in and add my experience do far.
Quick history- Been suffering hairloss for 20 years (37 now). Receded a fair bit but main issue is gradual diffuse thinning. Use nanogen regularly. Tried finestaride in mid 20s but stopped after 1.5 years due to bad sides. Hard to say if it done anything. Never touched minoxidil due to the hastle, cost, potential sides and need to apply daily or loose progress. Tried nizoral, hated it, bad shed made hair look crap so quickly quit. Tried oils (rosemary, lavender, peppermint etc) I believe there may be merit in these especially if dermarolling (not tried) but won't go near them again as makes my hair limp and thin for days and doesn't agree with nanogen.Take omega 3 and some apple cider vinegar most days. Saw palmetto small dose per day for bout 10 years.
Started magnesium tablets about 3 years ago due to muscle injury and knee pain, and started epsom salt baths (magnesium sulfate). Eventually noticed hair was looking better, or at least cosmetic appearance was better, seemed to give more volume. Added magnesium flakes (magnesium chloride) Have continued to this day. Use magnesium flakes mixed with water (diy magnesium oil, although it's not oily as such) to style. Hairloss steadied.
Read this thread and remembered I'd heard msm was good for skin and hair growth rate. Seen this thread then read up on it extensively on male and female hair/hairloss forums, seen very little in way of negative comments. So started taking 5-10 g per day 10 days ago. Made a spray and started spraying topically 2-3 times a day, 5 days ago (along with magnesium oil). Upped vitamin C intake.
I have a shockingly bad habit of running my hands through my hair once ot twice a day to see if any hair is shedding. Sounds rediculous but think its my way of subconsciously seeing if whatever I'm taking is causing a shed. Usually see a few hairs in hand. Sometimes a lot. However since starting msm not seen one. Literally none! Even when washing hair there's none in bath or sink (I bath in magnesium flakes and/or epsom salts, or use hot water in tub with same, never wash with just water).
Had mild insomnia first couple days so take at approx 8am and 1pm. (Anyone suffering badly with this, magnesium oil does the opposite and helps you to relax)
I realise this is no miracle so far and I'm open to ridicule but I'm certain the msm is strengthening my hair. I'm looking closely for regrowth and it's a bit early to tell but taking very close up pics it's seems I may be getting results. My hair is without doubt looking better than I can remember for years. But it's very early days.
Will post an update in a few weeks.
