Fresh rosemarry and basil leaves?

So at this point I cant buy any oils just yet, I intend to once I get paid but I have been taking my rosemarry leaves and basil leaves and boiling them into a tea, and pouring them on my dreads for about 30 minutes (after of course letting it cool down in the fridge and sifting out the leaves), I really only leave it on that long because I love the smell it leaves, but is this even an effective way to temporarily get some herbs in my dreadies?

I don't see why it wouldn't be effective. The oils are just more concentrated so you need just a few drops. Google how to make a tincture or how to make essential oils. They have to sit for several weeks, but you can make your own for a lot cheaper than buying them.

okay awesome!! thanks for the adviceee!!
