Does weekly deep-condtioning treatments repair hair damage

Conditioning your hair is like simonizing your car- it covers the scratches and makes it shiny!!
Conditioning coats the hair cuticle of the hair, easier to comb, and less flyaway, so it appears healthy, strong, and shiny.
The general rule of thumb is that the thicker and curlier the hair, the heavier the conditioner should be to coat it properly. Women with fine hair do best with a voluming conditioner and should avoid silicone.
Leave-in conditioners tend to be better for damaged and damage-prone hair because they add moisture without increasing friction from the extra handling required by the rinse-out variety.
Experts warn not to get too hung up on labeling "All the cream rinses and conditioners so the same thing"
