Neem in hair oil during pregnancy
(New Zealand )
I am planning to get pregnant later this year. Our family has been using a combination of essential oils, neem and vegetable oils as a hair oil once a week to prevent lice (very very effective as we live an area with a high rate of them).
The neem comes ready prepared in a natural oil called No Nits that is just made of plant oils. It is obviously not highly concentrated as you cannot even smell it (I know how strong the essential oil of it smells).
I am wondering if it is safe to continue using it on the head once a week for an hour, and if the precautions against conception are just do with vaginal and internal use of they include topical use on the scalp as well.
