I have been a hairdresser for 12 years. i warn against using olive oil it has been known to cause scalp problems if u use too much.

i would find a local hair suplyer get them to send you a list of their products or a catalogue, tell them your a hairdresser new in the area (what are they to know, they prob wont even ask) and find out if they deliver, if you have hairdressers in the area someone must suply them, and get it delivered to your door, my sister does this all the time you can buy awsome shampoo and conditioner and moisterisers in bulk mine lasts me almost 2 years.

buying cheap moisteriser wont do anything esp if you are using crappy shampoo and conditioner. the cheaper professional brands are better than all the supermarket ones.

oh and i like the CPR phase 1. to either leave curly or straighten it. i hate all the oils and never use them not even on clients. just get a normal hair shampoo (cause you have fine hair) and a deep moisture conditioner (for the curl) and keep it off your scalp remember using more conditioner doesn't do a better job just is a waste of product.

Good luck
