Hair Growth Remedies

I am in my thirties and could probably grow a full beard. I am so tired of getting it waxed and plucked but can not afford laser removal. Does anyone know of any good creams that can help remove hair permanently or even slow the growth?

I used to blow dry my hair all the time until I realized it gave me split ends and dryed out hair. Now I let my hair air dry all the time, but I want to let my hair grow long. I was wondering if air drying hair is good for hair growth?
