Greetings! Electrolysis is an outdated treatment. It is more permanent than LHR but can leave small scars or pigmentation in some cases. It is important to know that - did you get evaluated in detail for any hormonal imbalance...? because as long as that is not taken care of, you ll continue to have thick coarse hair and more and more of them. If you are over weight and have PCOD that has to be settled first...! See a qualified dermatologist near you; further queries may be sent on follow up messaging. Warm regards.
