What are the benefits n side effects of using high frequency comb for hair growth?

Don't believe: It will work. Is most likely a waste of your money big time. No side effects that i can think of for certain but it hasn't been studied.

Probably none: In terms of benefits and side effects , pretty innocuous from both standpoints. I've seen no evidence to date that this regrows hair. If you see something, please share it; however, keep in mind that your source should be a reputable journal, not a blog post or advertising website.

None: None, unless you count lightening your bank account as an advantage! these are about as strong as pointing a laser pointer at your scalp (which you should never do, naturally, nor near your eyes!) it doesn't work, and if it did, every dermatologist with hair loss in this country would be using them, but i know of none!

Try it!: This is controversial but harm could not cause. It should increase the local skin blood circulation with possible beneficial effect. I have a question however, have you been properly examined as to the reasons ur loosing hair? Did you see a dermatologist? If not go see one!
