First off, I love your curls! I think they look great!
Something similar happened to me. After menopause, my dry, frizzy, thick, stick straight hair developed random wave patterns, which totally freaked me out.
I've come to own it and love it. I wear my hair shorter now, and let it do its thing, whatever the weather (Humidity used to be my nemesis!)
About two years ago, my wonderful hairdresser turned me on to Alfaparf Milano products, which I love. I alternate using shampoo and conditioner from the brand's Diamond Range, which is pretty much an everyday s/c, with s/c from their curly hair range.
The Diamond range is great for people with normal hair, which pretty much fits me now (excepting the frizz), since I stopped coloring my hair during Covid. The curly hair range speaks for itself. Great for frizzy hair, and a bit more conditioning.
I love both, but my favorite product is their Sublime Cristalli Liquidi (an oil) with Thermal Protection. I use it after I shampoo, and sometimes on the ends of my hair when it gets a bit too unruly, or I want to redirect a wayward wave pattern.
All Alfaparf products have a gentle slightly floral scent, not at all heavy, that dissipate quickly. The products are very reasonably priced, and as someone who only washes her hair once a week, they last me a good long time.
