Are there some machines that you don't need to shave before getting Laser Hair Removal?

You will need to shave before laser hair removal no matter what device is used. Not shaving increases pain during treatment and risk of burning. Make sure you are being treated by an experienced provider. Best wishes.

Thank you for your question. You must shave before laser hair removal treatment. If you do not shave, the hair on the skin will absorb the heat and will not travel to the hair follicle. Also, not shaving can cause pain and increases the risk of burning. However during treatment you should stop tweezing and waxing as this disrupts the hair growth cycle. I recommend having a consultation with expert.  

You will need to shave before each laser hair session no matter which laser is being used. If you laser the area without shaving, the laser energy will go to the hair and not the follicle. This will make the procedure inneffective. Please make sure you are being treated by a board certified physician. Best, Dr. Green
