A heat activated weightless spray that can be used on damp or dry hair to create long-lasting, shiny, smooth, straight styles. Powered by our Healthy Hair Molecule (OFPMA), Straight:

  • weightlessly blocks humidity 
  • provides heat protection up to 450°F/230°C
  • is layerable and won't build up
  • helps to keep hair cleaner longer for straight styles that last

Straight is ideal for fine to medium hair types. It is silicone-free. Safe and formulated for color and chemically treated hair.


Start with damp hair that has been cleansed, conditioned and detangled. Hold canister 6” away from head and mist evenly over hair for 5-10 seconds. Comb and style with a blow dryer. Follow with a flat iron for pin straight styles. To use as a finisher, lightly mist onto your finished style.

Tips + tricks

  • To touch up and prolong the life of your straight style, apply to dry hair and use a flat iron or blow dryer as needed.
What makes Straight different?
Straight contains aerosolized OFPMA, Living Proof's breakthrough molecule. It creates sleek, smooth, shiny straight hair without the use of silicones or harmful chemicals. Straight is the only straight styler that can be reapplied to dry hair without build-up to extend the life of your style and extend your time between shampoos — for a straight style that lasts for days.

Does Straight build up?

Straight is weightless; it does not contain any oils, silicones or resins. It can be applied on both wet and dry hair and will not build-up.

How do I use Straight with other products?

Straight can be combined with any of your usual products, including shampoos, conditioners, leave-ins and other styling products.

  • For a full-bodied, voluminous style, apply Full Thickening Cream or Mousse to wet hair. Follow by layering in Straight.
  • For thick, coarse or curly hair types, first apply Satin or No Frizz Nourishing Styling Cream then Straight. When using Satin, a little goes a long way, so start with a pump spread through clean, wet hair. Heat style. For a pin straight finish, follow with a flat iron. Add more sparingly as needed to smooth flyaways and ends. When using No Frizz Nourishing Cream, apply generously from roots to ends. Heat style. For a pin straight finish, follow with a flat iron. Touch up with a small amount spread through hands to smooth flyaways and ends.

What is the fragrance?

All of our products have a light, fresh, citrusy fragrance.

How do I dispose of the hairspray canister after I use up the product?

It is safe to throw away in your regular trash.

I have used this product for a long time and then ran into some financial issues to where I couldn't buy this product for a couple months just to save. I noticed the difference in my hair when I stopped using this and when I started up again today I INSTANTLY noticed a difference. I'm never the kind of person to leave reviews even if they are bad... But having that immediate impact on my hair was just really nice and I want to share that. This product along with others I have used from the company work. I am and will always be a 100% satisfied customer!

My hair has never been so smooth & healthy since using living proof. All my coworkers are men and even noticed the difference in my hair! I keep a travel size in my desk of straight to touch up during very humid days. This is a wonderful product and worth every cent.

G0-to product for straight hair that lasts!

I have been using this product for a couple of years on my fine, super curly hair to help straighten and keep it straight...and I have always sprayed it on my damp hair before blow drying. I recently read that it can also be used on dry hair, so I tried spraying it on my second-day hair before I flat ironed it, going section by section, and it's wonderful -I was out in the evening on a humid night when the dew fell for the Fourth of July, and my hair didn't curl, kink, or frizz. (I also use the no Frizz spray on my finished style). Amazing!!
