6 sessions into treatment. Is laser hair removal working for me?

I have pale skin and black coarse hair and was a good candidate for great results. It was going great until there is now regrowth in all hairs treated. I know hairs grow back but some are growing back white and my dark hairs are finer and lighter. I'm 22 your male and I think my practitioner is using the polaris nd yag laser on me. The hairs are being removed but after a few weeks all the hairs seem to regrow but white and some really soft. Is laser hair removal working for me?
