TIL cold water rinses really do seal hair cuticles

I always thought this was just an old wives' tale with no real benefit. After a client with super shiny hair swore by it, I tested it on my own dry ends. The difference in smoothness and less flyaways after a week changed my mind. Now I tell all my clients to try a quick cool rinse at the end of their shower.

Man, we overanalyze these tips until they sound like a science project. From what I've seen, a cool rinse for around 30 seconds makes a difference for most folks, but ice cold isn't necessary. Curly hair tends to show more smoothness, but even straight types get less frizz. Just don't blast your scalp with freezing water unless you want a shock to the system.

So does this work for all hair types, or is it more for certain textures? I've heard mixed things, and it makes me wonder if the water temperature needs to be ice cold or just cool. Your test on dry ends is interesting, but what about the scalp? Does the cold rinse affect oil production or anything like that? It's funny how these old tips sometimes turn out to be true after all. But really, how long do you need to rinse for it to make a difference? A few seconds or a full minute? Just trying to figure out if this is a quick fix or needs real routine change.
