Just a few minutes into our chat with L'Oréal Paris Celebrity Hair Stylist, Mara Roszak, we were plotting to make her our new best friend. The obvious reasons: she has great hair advice and some ridiculous styling skills. The bonus: she's sweet, cute and mega down-to-earth.

We asked her a ton of questions like "Which celebrity tresses had she worked on lately," and "what hair trends are going to be hot this summer?" (Psst - it's braids.) When we asked about rejuvenating our strands in the heat and she started talking about the rinse-and-repeat regimen she suggests to her high-profile clients, we knew it was summer hair care gold. Our notes are below - you're welcome.

Step 1: Deep Condition Before You Get In The Shower
Coat your dry hair with your favorite conditioner (ours is Advanced Haircare Total Repair 5 Restoring Conditioner) and tuck your strands into a shower cap. Don't forget to bring this conditioner into the shower with you, you'll need it again in step five.

Change up your deep-condition frequency based on your hair: If you have thicker strands you'll benefit from doing this routine more often – even every day. Thin-haired gals can stick to one treatment per week. If your coif is color-treated, swap out regular conditioner for a color-treated variety like Advanced Haircare - Color Vibrancy Nourishing Conditioner. Also note that deep conditioning can cause color to fade, so to help extend the life of your color you may want to try a biweekly regimen.

Step 2: Do Other Shower Stuff
Shave. Soap up. Exfoliate. Basically, do anything except wash your hair for three to five minutes. While you're keeping busy, the shower cap-steamy air combo will let your strands soak up the conditioner.

Step 3: Rinse
This step seems pretty straightforward, but there are ways to fail at rinsing. Your shampoo can only do its job (to clean) if there is nothing in the way, like residual conditioner. You're ready to move onto step #4 when you can run your fingers through your hair, from scalp to root, and not feel any remnants of product. Your strands should be detangled, but should not feel filmy.

Step 4: Double Up Your Shampoo
Concentrate on your scalp where natural oils are being produced, and work your shampoo through the roots to create a base lather. Now, rewet your head and add a dollop more shampoo to build your lather. Choose a cleanser that's sulfate-free like Hair Expertise OleoTherapy Oil Infused Shampoo. Okay... Now it's time to rinse thoroughly.

Step 5: Re-condition
Starting at roughly ear height, massage conditioner down to your ends. Then apply the same rinse technique as in step #3.
