I'll be honest here, as an early proponent of Revita, I extolled its virtues on this forum for many of its purported good ingredients, but for whatever reason it made my scalp itch like no tomorrow so I finally gave it a rest. It also made my scalp really oily if I left it in for 5-10 minutes at a time while shampooing. Some might say that's a good thing, (the oiliness a good sign of hair health etc). Indeed, on paper Revita has a lot of nice ingredients of the "experimental" variety, and even a few essentials. I just couldn't deal with the itch personally. So I'd say if you don't experience itch with it, and feel like it's working, then go for it, but I stopped advocating it.
I'm now using a prescribed Nizoral 2% to shampoo with exclusively, and I add bags of Green Tea and a dollop of MSM cream to the bottle. So it's basically a proprietary mix of 2 % Ketoconazole, Green Tea, and MSM (sulfur). That in combination with my nutrition plan and Propecia is leaving my hair stronger than ever. The prescription for Nizoral 2% was surprisingly easy to get. I simply contacted my dermatologist and said I needed it to control seborrheic dermatitis on my forehead and scalp, citing that I had used Nizoral 1% OTC for a while and it worked moderately well but wanted to try 2%. Because I was an established patient, I didn't even have to come in, I simply called and she subsequently called my local pharmacy and authorized it. I've heard some people just found the right website and claim they have seborrheic dermatitis on their scalp and it will send it to them no questions asked. It's not a high risk prescription for any doctor or company so is relatively easy to get.I'd recommend going this way for shampoo personally, but to each their own.
With regard to Redken 'Extreme' conditioner (the conditioner you'd want of the Redken brand), this is another conditioner I discussed a while ago. Redken actually makes the claim that Redken Extreme Conditioner can and will repair and rebuild brittle hair shafts and add 2-4 times the width within a month, and most of its reviewers agree that it does work if you stick with it. I used it for a while and it certainly added shine and strength, although I didn't stick with it very long soon replacing it with Avalon Organics Thickening, Biotin B-Complex Conditioner which I still use to this day with good results. It's actually much cheaper than the Redken Extreme Conditioner which runs a little pricey $15-20 bucks for the small bottle vs the $10 bucks for the larger bottle of Biotin B Complex conditioner. The Avalon Biotin B Complex conditioner is loaded with essential 'hair loss relevant' ingredients as well (eg. Biotin, Saw Palmetto, Zinc, Niacin, Aloe, and Panthenol)
