Hey ho!

So I started using a castor oil & avacodo oil 50/50 mix in my hair a week or so ago. I've used it 3 times, I'd massage it into my scalp, leave it on for an hour then CWC it away but every time I did I found I was shedding alot more hair than I usually do. I was pulling out good 20 strand clumps while finger combing in my conditioner. I normally shed very, very little, I really do feel pushed to say I even usually shed 20 hairs a day.

Is this the castor oil causing this? Has anyone else had any rather unfortunate side effects with it?
