There is a down side to both. Shaving won't make the hair thicker, but it will be obvious when new growth appears. Plus, it may be a pain to keep up with. on the other hand, you have to wait until their is enough new growth to rewax. I would recommend laser hair removal. Usually you can see a difference after your first visit and depending on your specific situation, it can take as many as six to eight sessions. There are usually monthly specials at salons which offer this so you may want to call around. Another option, if the laser hair removal is not for you, is perhaps lightening the hair so it is less noticable.
