@AngelPuppy1 I noticed you wrote your hair "looks very parched and more frizzy than usual," but does your hair actually feel dry / parched? Could your hair just be responding to more humidity? For controlling my hair in humidity, I like Ouidad's Climate Control products. If you aren't familar with Ouidad, it's a brand mainly for those who have curly or wavy hair, but can be used by any hair type. I have wavy hair, but I have a friend who has straight hair, and likes to use some of Ouidad's products. The products that help to control frizz are Climate Control Defrizzing Shampoo, Climate Control Defrizzing Conditioner, and Climate Control Heat and Humidity Gel. You can find Ouidad at Sephora, Ulta, Beauty dot com, and other places (Ouidad has a website, too). Ulta has a travel size kit with all three Climate Control products that makes it easier to try, without investing too much in products you're not sure will work for you. It's $22 for the kit. That's actually what I bought the first time I tried Ouidad because my hair is kind of "challenging," and I didn't want to spend a lot of money on products I wasn't sure would work for me or not. (I don't like returning things). Below is the travel kit (you can read the details on Ulta's website) :
I, also, like Davines products. They have some really nice hair masks, if you would rather try a treatment.

And the Davines Oi line is wonderful. One of the ingredients is Roucou oil, which helps with restructuring. I use the shampoo and conditioner:

They also have an Oi Hair Milk and an Oi Oil product, but both of those products tend to make my hair too "soft." (I like "silky," but not "soft" for my challenging hair type). Davines also has many other great shampoos and conditioners, but I like their Oi line the best. Davines is mainly sold at salons, but you can also find them online at a few places (and at their website). HTH
