I would have all the organic/completely natural products that I want or need for my hair, no matter the cost. I'd also designate an entire room or area in my home for hair, nail, facial care. Basically, I'd have my own spa/salon on my property. I would fly in a celebrity stylist for special occasions, and hire my own personal stylist to do my hair on a regular basis. (Though money would be no object, I still find that I would be conscientious about what is considered a pure "waste of money," and not indulge in those things, no matter how much money I have at my disposal. I just don't believe in frivolous waste and unnecessary spending...I'd rather have that money saved in an account/buy some stocks with it/have it gaining interest somewhere).
I'd also buy the best Remy/Cuticle hair lace wigs, and build up a nice collection of them. I'd have an entire closet devoted to my wig/weave collection. OT: I adore shoes as well, and would also make my own shoe room/wardrobe room.
