I have a question for the community that I hope can be answered. What happens if you require your hairline lowered but all your donor hair is thick in caliber? Would it be wise to go ahead? Or, would softer hairs from your arms and legs be ok to use? I was told by a doctor that he can safely use these hairs but I'm not sure if this is true. I don't want to waste my cash on something that will end in failure.
