Thank you everybody for your precious comments , I think we will exclude the idea of bath oil as it seems to be bad idea.
but I have one more question please, can we use the combination between vegetable oils and Paraffin as Hair oil and if yes is it better to be used as a hair serum or hair mask? And what is the most suitable ratio between the veg.oils and paraffin?

@dodipharma mineral oil is apolair oil vegeteble oils are slighty polair so in liquid form almost you will obtain two phases .

Thank you very much 
if you have a better idea for the above formulation, I would be grateful.

Terrible idea to be honest. Hair serum and bath oil are two very different products and should be made of different materials. 

Hair serums are mostly made of silicones and oil is added at a tiny percentage for claims.

Bath oil should include polar esters and an emulsifier, otherwise, instead of milky emulsion, you will have oil floating in your bathtub like in a soup.

Or you can use literally any oil and market it as 2 in 1. This is going to be a bad product but there is no legal definition of what constitutes a hair serum or bath oil. The only requirement in this case is to mix oils with similar polarity because as Fekher mentioned above if you mix vegetable oil and mineral oil it will separate into two phases.

Thank you for your feedback ?
If we exclude the mineral oil , do you think its a better idea?
and which of the above oils have similar polarity ? Please advise

PeiHoong thanks for your answer,
Actually the formulation is registered as Hair oil bath but I want to use it as a serum as well.
