Protein treatment + hair gel combo does absolutely nothing to improve strength or hold?

I've been using the Aphogee two minute treatment plus the blue LA looks gel since January and it's done absolutely nothing. I use the gel everyday and the treatment every third day, which I've done for almost three months straight, and nothing has happened. My hair still has absolutely no hold when wet, when I tug on a strand it doesn't spring back into place and just gets straightened out. My hair most days is slightly curly in some spots and wavy in others. I know this isn't just my hair pattern because every once in a while my hair decides to work with me and actually randomly has strong curls when wet. As of now my routine in the shower is:

• Detangle with wide tooth comb
• Apply either shampoo and conditioner (both Garnier fructis) or the protein treatment, which I let sit for 3-5 minutes (I don't do them on the same days because that takes too long)

After getting out of the shower I:

• Apply gel to damp hair
• Apply Garnier fructis curl cream every other day to help with frizz/definition
• Apply dollar store heat spray
• Scrunch
• Blowdry

The only thing I can really think of is that the treatment isn't intense enough? Since the one I have is more for maintenance than recovery, but I thought that'd be offset by using it more than intended. It's supposed to be weekly and I do it every third day.

Thoughts?
