Stress + Surgery + Scalp and Thinning Hair

I noticed in the months after my hip surgery in September 2014 that my hair was splitting at the ends and felt less full than ever. I've never been Kim Kardashian in the hair department - don't get me wrong - because having naturally wavy, curly hair means inevitably frizz and dryness are two concepts I know well.
Scalp specialists and hair professionals both attest that stress, trauma and environment are key factors in the condition of the hair and scalp. Using chemical-laden products and heat styling only make a bad situation a zillion times worse.
The stress of knowing I would be out of work and also worried I might never do the more flexible yoga poses or the fully weighted squats I love built in the weeks leading up to surgery (I had planned it a year in advance). During recovery there was the stress of finding a new home, arranging to move, seeing family I don't normally see and having to accustom myself to crutches.

It's been almost a year and a half now and I am doing plenty of squats (heavier than before) and plenty of yoga poses (better than ever). My hair has still not fully recovered though. I have a plan of action, of course.
I will be setting aside the usual shampoo and conditioner and using non-toxic, 100% organic Rahua shampoo ($42.95 at Nourished Life) and conditioner ($43.95 at Nourished Life). I will also be avoiding over-use of the straighteners. That's going to be tough but I am determined!
I've also invested in six months of Maximum Strength Viviscal supplements ($179 for 3 month supply). Now, I am sceptical of supplements but I also know I see much clearer skin and have better energy when I take Fish Oil capsules and I have also noticed much more stable energy levels and better digestion when I take probiotics.

Viviscal regularly does clinical trials and have dermatologist approval and advocacy. There's nothing toxic or completely alien in their ingredients either. Based on marine extracts, the supplement is actually inspired by the Inuits - apparently they have richly luscious thick hair as a result of their fish and seafood based diets. So. Bring on the Viviscal maximum strength supplements daily, non-toxic hair products and a major serve of lobster. Stat.
