Oiling scalp before exercise - still effective?

[Forever_Sophie]

If I apply castor oil to my scalp then run for an hour, will it still work? (i.e. will perspiration prevent it from absorbing?)

I run in the morning and don't want to leave it on overnight 'til I'm sure I'm getting positive results from it.

I would think if anything your oil would absorb more easily due to the pores opening. However it's castor oil, the molecules of which I believe are too large to penetrate the skin or the hair cuticle/cortex, so I don't in this case it matters anyway that you are sweating.

Thanks for this info :)
