For all of us Geeks out there.. This is a cool scientific outlook on what mineral oil and other oils do and don't do to your hair.

Previously
published results showed that both in vitro and in vivo coconut oil
(CNO) treatments prevented combing damage of various hair types. Using
the same methodology, an attempt was made to study the properties of
mineral oil and sunflower oil on hair. Mineral oil (MO) was selected
because it is extensively used in hair oil formulations in India,
because it is non-greasy in nature, and because it is cheaper than
vegetable oils like coconut and sunflower oils. The study was extended
to sunflower oil (SFO) because it is the second most utilized base oil
in the hair oil industry on account of its non-freezing property and
its odorlessness at ambient temperature. As the aim was to cover
different treatments, and the effect of these treatments on various
hair types using the above oils, the number of experiments to be
conducted was a very high number and a technique termed as the Taguchi
Design of Experimentation was used. The findings clearly indicate the
strong impact that coconut oil application has to hair as compared to
application of both sunflower and mineral oils. Among three oils,
coconut oil was the only oil found to reduce the protein loss
remarkably for both undamaged and damaged hair when used as a pre-wash
and post-wash grooming product. Both sunflower and mineral oils do not
help at all in reducing the protein loss from hair. This difference in
results could arise from the composition of each of these oils. Coconut
oil, being a triglyceride of lauric acid (principal fatty acid), has a
high affinity for hair proteins and, because of its low molecular
weight and straight linear chain, is able to penetrate inside the hair
shaft. Mineral oil, being a hydrocarbon, has no affinity for proteins
and therefore is not able to penetrate and yield better results. In the
case of sunflower oil, although it is a triglyceride of linoleic acid,
because of its bulky structure due to the presence of double bonds, it
does not penetrate the fiber, consequently resulting in no favorable
impact on protein loss.
