Rosemary:
More revealing recent studies show that rosemary directly helps protect against hair loss. One 2015 trial Trusted Source pitted the oil against minoxidil, commercially known as Rogaine. Both were used on human subjects with androgenetic alopecia. Results showed that rosemary oil was just as effective a minoxidil. During the process, it helped the side effect of itchy scalp more successfully than minoxidil.
Another study Trusted Source of rosemary leaf extract (different from the essential oil) showed it stimulated hair growth. This occurred when hair loss was triggered by testosterone (as in pattern baldness). This study was performed on mice, however.
Two separate clinical reviews — one from 2010 Trusted Source and one from 2011 — also acknowledge rosemary’s hair growth potential. The former cites a study with successful hair regrowth in people with alopecia who used rosemary oil. One of these oils was rosemary.
In the latter review, rosemary oil was described as a hair loss restorative. This was due to its circulation-improving effects. Another study is linked below:

This is also revealed that most of the therapeutic properties of this plant are due to the presence of thymoquinone which is major bioactive component of the essential oil.
