Salon reco for thin hair ??

Hello, I'm looking for a salon recommendation so I could get back my confidence.
I have wavy hair but it is thinning due to hair fall because of my pcos. Gusto ko tani magpa rebond pero feeling ko it will look thinner pagid if mag bagsak. I am now considering getting hair extensions. Is there a salon you can recommend na may treatment, hair extensions and color??
How much do you think ang need nga budget?
