Hey Firefox, this definitely helps.

Looking for products with PQ-59 is fine, I will do that. There are other products that claim to protect from UV exposure as well, from blueberry extracts to shea butter to benzo-suchlikes and cinnamates - what's the word on those? I do usually use CJ CCCCL, which says the coffee in there protects a bit, as well as BRHG, which includes some cinnamates - but I am desperately on the lookout for something softer for the days I don't wanna be crunchy.

I do love half-ups, I have to work them back into my post-chop routine!

We're off to the sunniest island in Germany on the weekend so I'll work in a coconut-oil soak before we go!

One more question: How early/late in the whole process can a sun protectant be to still be effective? If I had a cowash with sun protectant ingredients, would enough of those be left in there, given I always leave more-than-a-trace of conditioner when I rinse, to have some effect? What about a coconut oil DT?

PS, some of the Buffs are definitely cute, I will look into ordering one or two!

My other concern with most sunscreens products is using enough to get a decent level of protection, think what a thick layer you are recommended to apply to your face and body, it's not a thin moisturising/ make up/ conditioner spray layer. There are many reasons you never see an SPF on a hair protection product, just very vague hints of what they might do.

Coconut oil as a deep treatment will help reduce protein loss from UV damage because of the affinity for structural proteins, but it's not providing UV protection. For example it likely won't prevent the protective cell membrane complex being destroyed, cuticle damage nor the melanin pigment being broken down which increases porosity. Some antioxidants (is that what you mean by blueberry and coffee extracts?) will protect from free radical damage but not against the other forms of UV damage, like chemical agents they get 'used up' or broken down quickly.
