So, in my stupor of exhaustion, I slathered on some of my DCs' strawberry hair conditioner. Not the posho ones I usually use, no. Just the pink, smells-of-strawberries-but-not-really stuff.
My hair is softer and smoother than ever.
Another one, instead of buying all the pricey paraben-free stuff I used to by, is to get Boots own baby wash. Smells nice (gentle smell), does the job, no mad dryness either. £1.99 a pop. I used it when my own stuff ran out.
Can you see a theme here?! 
Do you have any to share?
