Hmm, i will try this also! It's hard to find out one is making the right concentration. Say I'm going to be useing coffee (because it is readily avaliable). How do I know i'm useing the right concentration? I won't!

Like it doesn't state the percentage of caffiene in the coffee does it!?
If it does. For example, if coffee is 10% caffiene, 100g would be 10g caffiene.
Then I would need to dilute that in how much water? 150ml? To get 0.15% solution? I'm not great at maths!

So confused! I don't want to halt growth!!!! I could see myself applying it to the scalp even after a wash, as I use herbs and I leave a light coating of sebum on my head...just because it makes my hair soft. That would help it stay a bit less gunky of it is drying. Even I can see myself applying the night before a wash if I find it leaves my hair gritty feeling.
