What is Prime Style Extender?

Prime Style Extender is a breakthrough, first-of-its-kind hair primer that extends hairstyles up to 2x longer. It reduces the need to touch up hairstyles and keeps your hair cleaner longer, reducing the need to shampoo as often. Prime Style Extender detangles, perfects, and corrects cuticle texture and thoroughly primes and creates an optimal base for styling.

Does Prime Style Extender work on all hair types?

Prime Style Extender is a universal product that works on all hair types to prime hair for more perfected and longer lasting hairstyles.

How do you use Prime Style Extender?

Your hair style is created by wetting and drying your hair, which sets hydrogen bonds into a desired shape. Your style will stay in place until these temporary hydrogen bonds are broken by moisture leaving or entering the hair shaft. This movement of moisture into and out of hair is called moisture flux. This phenomenon happens to everyone throughout the day, every day of the year because moisture levels in the environment around us are constantly changing. Prime extends hairstyles by blocking moisture flux, preserving hair’s hydrogen bonds and therefore your hairstyle. 

Will Prime Style Extender weigh my hair down?

No, Prime Style Extender will not weigh your hair down.

Does Prime extend all hairstyles?

Yes, Prime Style Extender extends all styles such as straight, smooth, curly and volumized.

Can you layer Prime Style Extender with other styling products?

Yes, Prime Style Extender is so perfecting it can be worn alone, yet so weightless it can be layered under other styling products. Always start your styling routine with Prime Style Extender.

Does Prime Style Extender provide heat protection?

No, Prime Style Extender does not provide heat protection.

Does Prime Style Extender provide UV protection?

No, Prime Style Extender does not provide UV protection.

Is Prime safe for color or chemically treated hair?

Yes, Prime Style Extender is safe for color and chemically treated hair.

Can I use Prime Style Extender with a leave-in conditioner?

Yes, you can use any leave-in conditioner before Prime Style Extender for added conditioning and detangling.

What is the technology in Prime?

Prime is a highly efficient delivery system for our miracle molecule, OFPMA, which is clinically proven to:

  • Create an exquisitely thin, weightless shield around each hair strand
  • Limit the disruption of hydrogen bonds by controlling moisture flux
  • Repel dirt and oil to keep hair cleaner and styles lasting 2x longer
  • Provide priming emollients that corrects hair texture, detangles and increases resistance to breakage

OFPMA is proprietary to Living Proof meaning no other hair care companies have this same technology, so they have to rely on other ingredients such as heavy oils and silicones.

love notes

Love, Love, Love SL Style Extender
Posted by Mary E on February 06, 2018

I got this full size tube in my last order I think it was May 2017 and still have plenty left because I have short hair. It does exactly what it says it does, extend the life if your style. I use it and then add 5 in 1 over top of it. Even with short hair my style lasts almost a week. I have been using a consideraby higher priced shampoo but am switching to LP shampoo/conditioner with this order. Also have the pre-shampoo treatment, the LP full dry volume blast spray, the LP full thickening cream and the thickening mousse. Most often use the pre-shampoo treatment, the style extender, the 5/1 cream and the dry shampoo. But think I will re-look at the products I have on hand and think about using them more fully. Ordering SL texture spray, styler and the shampoo/condition in the PHD format.

Prime your hair!

I am a big fan of hair primers but I never expected to use one that had the added benefit of keeping your hair cleaner longer. I always used a primer just for blow drying. You can use this for heat (use more) or air (use less) and have clean hair to boot. I only wash my hair every three days anyway but I can go longer using this product if I choose to do so. It will come in handy in the Winter on workdays when I don't feel like getting my hair wet when it is cold outside and I can sleep in longer. It will come in handy when I go on vacation and I don't want to spend time doing my hair every single day. I put about a quarter sized for my below shoulder length medium-thick hair right after I towel dry when my hair is still very damp and then put in a smaller amount of styling product while it is still damp prior to styling. I purchased a full size after trying a mini sample - it's great!

Actually Works!

This stuff is amazing. I can use this after washing my hair, then styling it and I can depend on the fact that my hair will still look fabulous the next day and even the next. Worth every penny!
