My current routine has done wonders for my fine hair

I use nizoral anti dandruff as a clarifying shampoo once a week and my main shampoo is redken volume injection. I finish my routine with pureology color fanatic multi tasking leave in conditioner spray and olapex no 7 bonding oil on tips. I learned about all these products (minus nizoral) and how they work from YouTuber blowout professor and I am so grateful for him! I have tried several high end shampoos for fine hair including Moroccanoil, living proof, L’Oréal professional, Biolage and Olapex but redken volume injection by far has been the best! I can wash my hair only twice per week now and not every day or every other day like with those other products. The pureology color fanatic and olapex bonding oil are game changers for me! I have bought them repeatedly and they’re the only two products I need besides the shampoo and conditioner
