MEN LOVE THE SMELL!!!! - GREATEST SMELL IMHO BC OF COMPLIMENTS THROUGHOUT 27 YEARS AND I LOVE IT TOO!!! IMHO I DO NOT IT IS AS MUCH FOR STRAIGHTENING HAIR WITH A HAIR DRYER (add a little water to it in your hand; go to end of my Review for more instruction plz), BUT IT WILL TOTALLY DO IT BEAUTIFULLY (Experience there, too)! It is BETTER FOR PPL WITH CURLY WAVY FRIZZY HAIR WHO WANT A TAD OF CONTROL WITH SHINY BENEFITS!! Heehee! THE BEST PRODUCT EVER - WORTH EVERY PENNY!!! ALL COMPLETE TRUTH!!! I have been using this RUSK STR8 for 27 (it MIGHT BE LONGER bc my Son just turned 31 & I started when he was a Baby or almost a Toddler!! I kid you not!)!!! I was a Legal Assistant in SC & a Co-Worker with EQUALLY LONG, CURLY, FRIZZY HAIR - hers was Natural Red, mine Dirty Blonde - came up to me & SHE TOLD ME TO START USING THIS PRODUCT BC MY HAIR WAS TOO FRIZZY!! She was direct, ALWAYS SPOKE HER MIND, so I took her advice & never looked back! Why? There are SO MANY REASONS!!!! It IS SOFT, not stiff like SO MANY anti-frizz hair products, making it effective on ALL LEVELS (redundancy, yes!!)! Makes your hair soft and curly without crazy Bobby-pin frizz fly-aways (Tribute to the Crazy Witch on Old Bugs Bunny Cartoons! Haha!), my Hair DOES SHINE, giving me like a BRIGHT AURA (you need to KEEP SMILING LADIES AND GENTLEMEN, too, bc WE ARE TO GLORIFY GOD IN ALL WE DO, right?) GIGGLES AND LAUGHTER AND SMELLING GREAT!!! I cannot tell you HOW MANY MEN HAVE TOLD ME HOW GREAT - NOT Good, but GREAT!!! - I SMELL!!!! The product IS thick, but I just use a little at a time on my FINGERTIPS- OR, use a little more in the Palm of Your Hand, ADD A LITTLE WATER INTO YOUR PALM AND MIX, BRING TO YOUR FINGERTIPS AND SPREAD LITTLE BY LITTLE TO YOUR BEAUTIFUL CURLS!!!! I KNOW it PROTECTS YOUR HAIR FROM LITERALLY ALL WEATHER CONDITIONS - unless you’re standing in pouring rain!!! - in which case, you need more than Hair Products to help you!! Lol. HOPE this all helps - I had to leave a Review when I saw some negativity in the Reviews because ALMOST 30 YEARS OF USING A PRODUCT IS NOT SOMETHING TO BE TAKEN RUSKLY!!!!! Hahahaha!!!! Review: Smoothens without weight - So far, I really like this hair treatment it definitely helps take the frizz out of my hair during this humid weather. I have super long normally straight/ slightly wavy hair that is very fine and gets tangled very easily and the stuff just makes it nicer. It definitely makes it straighter and makes it look very neat. I don’t have to blow it out with a round brush as much as I would so it cuts down on time and just makes my hair look better. I wish it had a better smell. The smell is not bad, but I just wish it was better. I will definitely re-purchase. ## Features - Smooths & Straightens - Lightweight hair lotion & blow dry cream helping to control frizz, smooth texture, reduce puffiness, and support sleek, straighter styling with added shine and humidity defense. - Designed for Frizz-Prone & Hard-to-Manage Hair - Use our blow out hair lotion on curly, wavy, thick, coarse, and humidity-sensitive hair needing smoother texture, blowout support, and frizz control during styling routines. - Lightweight Styling with Thermal Protection - Hair smoothing cream helping to support heat styling while improving manageability, shine, softness, and smoother-looking texture without greasy residue. - Easy Blowout & Straightening - Apply the smoothing cream for frizzy hair evenly throughout damp strands before blow drying; pairs with brushes, blow dryers, and flat irons for sleek finishes and humidity-resistant styles. - Trusted Professional Brand - RUSK is known for high-performance hair care solutions; formulated without heavy buildup to support clean, flexible styling results. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000VIX9NQ | | Best Sellers Rank | #26,466 in Beauty & Personal Care ( See Top 100 in Beauty & Personal Care ) #240 in Hair Styling Creams & Lotions | | Brand Name | RUSK | | Customer Reviews | 4.4 out of 5 stars 1,754 Reviews | | Global Trade Identification Number | 00611186025338 | | Hair Type | All | | Item Form | Lotion | | Item Volume | 6 fluid ounces | | Item Weight | 6.08 ounces | | Liquid Volume | 6 fluid ounces | | Manufacturer | RUSK | | Material Type Free | Gluten Free | | Number of Items | 1 | | Product Benefits | RUSK hair care products can be used on all hair types to bring back vitality to fine, limp, and faded hair.
