This is great for anyone who has straight to wavy hair and blows their hair out on a regular basis. After a shower, towel dry your hair and work a dime size of the product through your hair - avoiding the scalp. You might need more based on how thick your hair is and how much you have. Take a wide toothed comb through your hair from to make sure the product is distributed - always make sure to start combing from the bottom. Then start blowing out your hair the way you normally would. This protects your hair from the heat, helps keep the shiny, and greatly diminishes chances of frizz. (How you blow out your hair can have a huge impact on how much frizz you have. If you're still frizz after a blow out, you may want to consult YouTube to work on your blow out technique.) I have used this with a flat iron and I remember it working well, but I haven't used a flat iron for a really long time. I thing this would work well, but you would also need to remember the golden rule of not using the highest heat on the flat iron - most wavy girls should go no higher than what looks like the "medium high" setting.I have been regularly blowing out my hair since I was 14 and have tried many, many hair protectors, but always come back to this one. I have had my hair died some fantasy color another for the last 10 years and I credit this product (in addition to my amazing Aquage color care shampoo and conditioner) for helping maintain my shine and color between treatments. The best thing about this product is that it that your hair still feels like hair after using it - not sticky or hard whatsoever. I found the creme formula to be light and I run my fingers through my hair right after I'm done. I think the secret to less frizz and for you hair to stay how you styled it, is to have a really good shampoo, conditioner, and touchable leave in product. This one might be your one out of three :)***Please Note: CURLY GIRLS HAVE DIFFERENT TEXTURE AND NEED DIFFERENT THINGS!!! This might do well as a basic de-frizzer, but the best products I've found to manage and bring out the best in your waves and curls (all the way through 5C texture) belongs to LUS Brands products. Talk to one of their reps, follow the steps, and keep those beautiful curls flawless*** Read more

Not only does this product smell terrific, but it manages to control my curly hair without any stiffness. I can let my hair dry naturally and I have soft curls but no frizz, or I can blow it dry to give a straighter look. Read more

Excellent quality haircare product just like at the salon without the hassle of going to the salon. I compared it to an old bottle I have been hanging onto and same formula. I even use it without blow drying and just flat iron while using another product and I love the silky smooth result. Doesn’t flake on me when wet to dry without blowing dry. Read more

My hair was literally fine and broken. After washing hair, putting a dab of Behave throughout my hair, and diffusing my hair, my hair felt great. I followed up with a round hair-drying brush. I actually had "swing" hair; something I have never had. Read more

Biomega is great at taming my frizzy hair after shampooing. It was recommended by my stylist & I love it.What wasn't so great was the seller's (Amazon.com Services LLC) packing. While the product was wrapped in a plastic bag, the lid was very loose and product squirted out all over (very messy cleanup). Found the cap wasn't screwed on at all! Read more

Have used this product in past, but won’t be using this bottle. It arrived with no pump and an opening in the top - some of the liquid had seeped out. Expensive product that I must try to return. Disappointed - why would someone knowingly package this defective bottle?? Read more

This product is worth its weight in gold!! Definitely all 5 stars. However, the 3 star rating given is due completely to packaging and delivery. When the package arrived, the bottle was open and half of the product had spilled into the packaging. I had to scoop as much as possible back into the bottle. Read more
