shampoo and conditioner recommendations?

currently I use the shampoo and conditioner posted in the first slide (Kristin Ess Signature Salon) and recently i've gotten what I think are clogged hair follicles. I wash/condition my hair every other day and use a Wet brush once or twice a day. I was thinking about getting OGX thick and full biotin and collagen (second photo).

has anyone used this? any recommendations for a good (affordable) shampoo and conditioner? my hair is about shoulder length and not color treated. tia!!!
