Use Wella SP (System Professional), especially the 30-second
Conditioner which is to be used once a week. It works like a DIY
hair-steam, so it protects my hair well during the months between
my hair treatment sessions.
Before u step out of ur house everyday, spray on Tigi Protein
Protective Spray -- it'll keep ur hair conditioned the whole day.
Both products are sold only at salons, and cost below $20 each. I
guess they should work well to optimise the quality of ur
hair.
In the meantime, stay miles away from chemical treatments that'll
further damage ur hair.
For your face, maybe try Sage & Comfrey Blemish Gel from The
Body Shop.
Hope the above comments are helpful and good luck to you!
