Here is how I am thinking about conditioning vs. deep conditioning hair. It depends on the following:
a- How porous/damaged is the hair system (highly to normal to low)
If you have low to normal porosity hair, in most cases you can just condition the hair with an occasional deep conditioning.
If you have highly porous hair, then you can do regular deep conditioning until the hair is healthy again. You can also use a cream based leave in conditioning as well.
b- What is the hair texture
If the hair is porous but fine to normal, then you can just use conditioner . A deep condition can over power fine hair.
If the hair is coarse and porous then deep conditioner and conditioner is advised.
What is your method? please share…
