Hair Growth Remedies

Is there any product out there that actually inhibit or atleast slows down the hair growth (underarms, legs, etc.). Please don’t suggest laser hair removal and etc. its too expensive . Im looking for a cream or a lotion?

i have 9 months old baby girl and have been told by my friends that shaving her head once in every 15 days incereas the hair-density and after some years she will grow silky soft hairs. Is the heridity anything to do with the hair growth and it’s quality. I would like add that i have silky hair. and i want my child to have better hairs than i have. Please comment on this.
