One of the most difficult parts of blending essential oils for perfume is olfactory exhaustion.
When you’re blending essential oils to try and find *just* the right proportions of each, it’s not uncommon to completely overwhelm your nasal passages.
On top of it being probably not too healthy for you to huff undiluted EOs for extended periods of time, it can be:
- Wasteful: when you’re experimenting with neat (i.e. undiluted) essential oils and you don’t like the result, your blend will probably end up gathering dust on the shelf
- Misleading: once you add a carrier, your blend might not even smell the same as it did undiluted
