Tizz here is a bit more information about HBO. If one is in the individual chamber, then one changes to scrubs that have been washed in special detergent. No lotions, hair preparations, makeup, jewelry, or anything else is allowed inside, including and especially paper, as in books. In an oxygen rich environment every effort is made to eliminate even the smallest risk of static, for obvious reasons. Entertainment options are limited to music or watching videos through a curved glass. In a multi-place chamber however, there is much more leeway and I have known people who were able to read. This treatment is used when teeth are pulled, or in my case, implants placed, because the high level of oxygen causes new capillaries to form, bringing more blood to the bone, which allows it to heal. The effect lasts for about a year, then the healed bone reverts to the previous state, which is fine if there is no trauma. If you ever need this treatment, contact me and I will give you some helpful hints.

About hair, I lost mine and it came in frizzy and dry for the first few inches, then reverted to normal.

I want to visit your warm beaches too!
