There are certainly differences between places, not only in the equipment they use but also in the training of the technician. There are a few common themes I have seen for successful laser:
- Appointments need to be spaced out, 4 - 6 weeks between appointments seem to the usual.
- Usually, a minimum of 6 sessions is required, so this can be a 6 - 8 months process
- If you have jet black hair as described, it should work pretty well.
- Electrolysis is usually something you can save for the occasional stray grey hair
I had 6 sessions on my face using a Candela GentleLase system (also seems to be very common in better places, it uses two different wavelengths laser to improve results). This took care of all the black hair and it has not come back after 4 months. I am now into Electrolysis due to half my hair being gray/white.
I know Laser does not work for everyone, but for me, it has worked really well. I was initially looking at cheap places via Groupon, but ended up deciding for a highly recommended place around the corner. A laser session is $125 and electrolysis usually $59. I did negotiate deals and pre-paid a larger number of sessions which significantly drove down the price. Full bottom hair removal is $1,500 which will be a combination of Laser and Electrolysis. By the time I had my face and bottom done, I will have paid about $3,700. Lucky my arms and legs won't need any treatment.
