1. First of all, do you use always use heat when you deep condition?
Yes, always
2. What sort of heat do you use? (blow dryer, heat cap, hot towels) etc.
Steam, it is the best way to deep condition imo
3. Do you use a special 'deep conditioner' rather than a normal conditioner?
I use intensive conditioners - they are the only conditioners I own
4. Do you add other things to your deep conditioner?
Not really, but I have sometimes added drops of oil, meadowfoam seed oil and strawberry seed oil, the latter gives the hair a lovely fragrance
