Any alternatives possible ? As a student these are very heavy on my pocket

These have somewhat worked for me and paused my hairfall, 1 month dose was about 8k by the Derma. Can I just continue with some alternatives ? I'll get the shampoo and the Hair serums off Amazon, they are not that expensive but the Biotin Meds on the right are very expensive. Can I just start Supradyn, fish oil, Vitamin D3 B13 tablets as suppliments ?
