why the different penetrating abilities of ionizing radiation through paper, aluminium and lead?
they both do, most straightners have ceramic platesI'd suggust investing in a chi, they range from 90-120$they work the best and aren't that damaging
yes they doim a hairdresser and we use them in my saloni would suggest using the ceramic plates as they are much better for your hair and don't leave your hair as porous (dry hair) the plates help to condition your hair leaving it smooth and shine and non greasyhope this helped
Bedhead I know for sure has ceramic platesI use them in my salonThey're really a good straightener considering they aren't the Chi, brand!
I actually have a friend who manages those kiosk thingys in the mallHe was telling me that there are only a handful of straighteners out there that have real ceramic platesThe rest are just coated with a ceramic type 'paint' if you willThe Amika (what he sells) does not have real ceramic plates eitherHowever, he says that the 'coating' is more durable with more even heat dispersionGo with that oneNow matter what tool you use straightening your hair is HORRIBLE do a deep conditioning treatment of olive oil in your hair once a weekAlso, when straightening, run a comb behind your hair after the straightener it makes it work better with less damage! Best of luck!!
energy loss goes like Z^2, so the higher the average charge of the absorber the higher the energy loss, hence the smaller the range paper Z~6 (C+H) aluminum Z13 lead Z82 the Z^2 dependence applies to charged particles (alpha, beta, etc) however, similar range relations exist for gammas - whose energy loss mechanisms (compton scattering, photoelectric effect, and pair production) also effectively increase w/ the Z of the absorber cheers
