- Q
I usually straighten my hair blow dry then straighten when do i use this? do i use the heat protectant before or after this?
- Asked by Heat queen
- Official Answer By Redken - BEHi there! Thank you for reaching out about our Redken Extreme Length Leave-In Conditioner. When you're using the Redken Extreme Length Leave-In Conditioner with your blow-drying and straightening routine, here's the best way to apply it: You should use the Redken Extreme Length Leave-In Conditioner before you blow-dry your hair, on damp, towel-dried strands. It helps to detangle, strengthen, and prepare your hair for styling. Regarding heat protectant: If your Redken Extreme Length Leave-In Conditioner provides sufficient heat protection (check the product details), you might not need an additional product. If you're using a separate heat protectant, apply it after the leave-in conditioner and before you begin blow-drying or straightening. So, the order is: Leave-in on damp hair > Heat Protectant (if separate) > Blow Dry > Straighten.Was this answer helpful to you
- Q
I typically use a spray leave-in as a detangler. Should I use this product or the Anti-Snap leave-in or both together?
- Asked by Melanie
- Official Answer By Redken - BEHi there! Thank you for reaching out about our Redken Extreme Length Leave-In Conditioner. For detangling, our Redken Anti-Snap Leave-In is a great choice as it's specifically formulated to help reduce breakage and aid in detangling. Our Redken Extreme Length Leave-In Conditioner primarily focuses on strengthening and promoting length, though its smoothing benefits will also help with detangling. You can use Anti-Snap for direct detangling and breakage protection. If you also seek significant length benefits and intense strengthening, you can use Extreme Length as well, but always observe how your hair responds to avoid product buildup.Was this answer helpful to you

Yes! Please!
First and foremost, I love the scent of the shampoo! It's a cotton candy-ish smell, but not overwhelmingly powerful. It lingers forever, I've never gotten so many compliments on how great my hair smells!! I have waist length, thick THICK, wavy/curly hair. It's pretty coarse, hard to comb through, a...

Tames frizz (I think)
I received this product to try for free in exchange for sharing my opinion about it. I have fine hair that lacks volume, as well as certain pieces that don't really seem to be growing at all, so I was very excited to try out this product line. For two weeks, I used this leave-in treatment in conjunc...

absolutely amazing!!!
Let me start off by saying my hair was freaking fried after over bleaching I went to 3 different hairdressers the 1st one messed my hair up so I went to the second hairdresser she fixed it then told me to hold off on the bleaching, of course my dumb self was impatient and went to a third hairdresser and she bleached it and it fried/broke off a good amount of my hair. I started using the redken acidic bonding which I love then a month after I started using this extreme lengthening leave in conditioner and the shampoo. I have 2c and 3a curls combined and let me tell u my hair went from fried stiff texture to my normal wavy to curly hair shape with no frizz after using this extreme lengthening line after the second wash! I cried of joy! thank you redken!
Burnt
BURNS and made my hair fall out
No change
I have long fine wavy hair that tangles easily. I was looking for a product to make combing easier after washing. Bought this based on reviews and my hair is no easier to comb than if I used no product at all. Will not purchase again.
Seal the ends and miss a few trims
