I've been using CK for about 4 yrs now. It keeps my hair frizz free in any weather. We don't get winter here in SE Florida so I don't know what would happen in freezing COLD weather.
It's the BEST! Actually afraid not to use it.
I get 3 days of pretty good hair from using:
1. Just about any leave in KBB nectar (favorite) CJ 2nd.
2. CK a good amt
At night pinapple in AM spray with water with a little KBB nectar in it.
Good to go! So easy!
