I tried to wax my head using some lady leg wax last year. I did it at the end of September with a lot of pain and little result so I tried to let it grow longer like the instructions said. I waited a couple weeks and tried it again and a few hundred hairs came out but it wasn't noticeable. About 4-5 days after doing it for the second time I was washing my scalp which was very sore and looked sunburt I used a scrubber on my head with axe exfoliating body wash and hair was just falling out like crazy. I quickly earned the name 'patches' at work because I had tons of smooth patches that were random sizes/shapes. That was in the middle of October, the hair didnt start to grow back in the patches til early March.
If you get it waxed successfully it would last a couple few months atleast.
I checked out the video, looks really painful for me. Great new pic by the way. If you go ahead with your plan, I hope you are satisfied with the result. Best regards.
To reiterate what Razor X said before you made your decision--the right one

--it will take care of itself as part of the balding process. But, if you go ahead, be sure to keep it very clean, sometimes infections can develop when hair is ripped out by the roots.
It was VERY painful. There was lots of blood seeping through the pores on my scalp. I tried the whole scalp but it just wasnt happening, it thinned it out somewhat though. The hair grew back for the most part but I can still tell where they are because I think some of the follicles were damaged.
Glad you kept the sly and it does look good on you. Welcome Ben
