Alternating Dut and Fin?

[Nyhair19]

I have been using Dut once a week since about April after noticing some thinning. I have been on Fin for about 10 years and was worried it's losing its effectiveness. Some people said they saw benefits from Dut once a week, so I added it. However, after almost five months, I am not so happy with the progress and am not sure it's doing anything. I don't quite want to make the jump to Dut yet, so I was wondering if anyone alternates Fin and Dut? Some people I know take Dut every other day, but this is kind of uncharted territory as there's not many study of these.

Any thoughts would be helpful.

Cheers
