Are collagen peptides worth it?

I started taking the vital proteins collagen peptide powder, 2 scoops, every single day..without fail..since the end of December. The reason I even jumped on it was to help with my pp hair loss and my brittle, terrible nails (also a pp issue) I'm now 7 months pp and I've been taking this religiously for almost 7 weeks. Do I just need to give it more time? Will it actually help..or is there something better for hair & nail growth? Am I wasting my money? Help me 😂
