I think its not very popular anymore because of laser just my opinion x
That's simply not true, I am still doing electrolysis on a daily basis, and there are plenty of salons offering electrolysis round here. I think the reason it is seen as less popular is more to do with the way students are trained now, whereas electrolysis used to be a compulsory element of an all round approach to training, a lot of people tend to train only in particular areas. There are simply less electrologists trained now, and a rise in salons offering just nails/lashes etc.
When it comes to lip and chin hairs, electrolysis is chosen by most people over laser as it's generally less expensive. Here is a comparison of electrolysis and laser/IPL:

Moreover, most people who have laser will have hairs remaining following treatment, which most laser technicians will then recommend the client has removed by electrolysis. There are others still who have hairs that are not successfully treatable by laser, such as lightly pigmented hairs. For this reason most laser clinics also have an electrolygist.
Also, electrolysis is still the ONLY proven method of permanent hair removal.
Not only that, but electrolysis training also opens the possibility of later training in the use of diathermy and blend technique to remove and reduce thread veins, skin tags, warts, verrucas, moles, age spots, senile warts, milia etc etc.
