Hey hey! K, so I asked Andrea (the owner of RHE) and she says they're different companies. But when I went to the RHO store in Amsterdam, the sales lady said RHO is Andrea's husband's company and RHE is Andrea's. I dunno...confusing for me. I went on a limb and got the RHO even though I trusted and wanted RHE since I bought my KC from them last time.
After buying the Real Hair Online hair in the Amsterdam shop and installing it, it seems exactly the same as the RHE anyway...so I'll see how it holds out in the long run. I loovvved Andrea's hair and *every* body thought it was mine...like girlfriends I've had for ages. I highly recommend them. The only other KC I've tried is BoBraz. It was my absolute favorite weave purchase ever...for the first week. After that, it was a weird tangled mess. I'd never go back to it after using RHE.
Both the RHE and RHO are dense, but maybe it seems that way because I have a small head, haha. For my tiny head, about 5 pieces (1 piece is about 1oz) works fine for me if I'm doing a full head. I don't think anyone would need more than 8 unless you just really really need massive hair. And it puffs up like black people's hair, so I think more than 8 is tooo much.
