which oil is good for Hair:

There are a huge number of oil extracts that we see,

The oil that we apply on hair should make it healthy , shine, focussed on tips, lighter and free flowing

The most successful oil product company uses

* coconut as primary - provides shining
* neem oil - makes healthy
* Tulsi oil - gives great fragnance

and some more may be used ,please let us know,

Really all oil does, is lay on top of the hair and hold in your body's own moisture in your hair. The molecular structure of oil is larger that the openings of your hair shaft. So I don't think it really matters, the oil just forces your body to produce it's own natural oils and take care of your hair.

I will have to agree with the coconut oil.  It is really nice and doesn't weigh down my hair.  Though olive oil was used on my hair once and it didn't look bad at all.  But my mother used coconut oil all of her life and I have continued with that tradition and expect my daughter will do the same.
