Wavy, thick, coarse, gray hair  No problem! I LOVE 3Day Straight!
I have long, thick, coarse gray hair. I’ve been using this product about 6 years now. I live in Louisiana where 85% humidity is “dry” air. I have a hay-stack without this product- and properly used (flat ironing small sections at a time) it will “last” until the next time I wash my hair-7-10 days. I LOVE THIS PRODUCT and would give it 30 stars if I could. I’m not going to lie and say this makes anything “faster”  -I actually spray my hair after towel drying, detangle with “WET”brand brush,  and let it air dry a couple of hours while I do other stuff and it is the best detangler I’ve ever used. Since that was my main reason I conditioned my hair, I’ve eliminated one step from my washing process, but guess what? No conditioner keeps my hair cleaner and oil free longer. It is most effective at a high setting 380 to 400 degrees and you have to be patient and iron small sections at a time. I buy it in multiples because I’m terrified of running out and was disappointed but not surprised to see it has been discontinued on most store shelves, which is why I just ordered here.<br />It isn’t that they are simply out- there was no sku#  label on shelves for this to show it is supposed to be there.<br />If you get professional Keratin, this extends the life of your Keratin exponentially. I love this product.
