Beginners query

I recently had a consultation with a hair system specialist. They recommended I go for the thinnest possible hair piece to match my natural hair.

To save on cost I would like to try to do this myself. I am also very far from anywhere that does this so it would make more sense to do it myself.

I have also decided to go with a frontal system. I know it is a hassle but I only have temple recession.

From what I gather, a lace system would be best.

My query is, where online would you recommend for purchasing a very thin lace brown system.

Thanks!
