Concen-straight Smoothing Treatment


Concen-straight Smoothing Treatment

What it is: A single-use product that smoothes hair for lasting manageability and frizz reduction. What it does: Formulated with patent-pending Concen-straight Technology(TM), which helps maintain hair's natural integrity, this formula smooths hair for manageability and frizz reduction for up to 30 shampoos. Concen-straight was created to let you style your hair as straight as you like it. Once you've given yourself the treatment, it's up to you how straight you'd like to style your hair. Flat irons render hair pin-straight, blow dryers create body and movement, curling irons create smooth shapes, while air drying reveals natural, more manageable texture. What it is formulated WITHOUT:- Parabens- Sulfates- Synthetic Fragrances- Synthetic Dyes- Petrochemicals- Phthalates- GMOs- Triclosan What else you need to know: Hair type and condition are extremely important to consider before you use Concen-straight. Though gentle, this treatment alters bonds and exposes hair to high heat. For clients who color their hair: As with any chemical treatment, this treatment may cause color fade, especially in redder tones. In order to avoid shift in color, you must use Concen-straight first, and then wait two weeks to have your hair colored. For clients who chemically straighten their hair: Wait six weeks after any professional straightening service to use Concen-straight Smoothing Treatment.For clients who have fragile or bleached hair: Hair that has been bleached, double-processed or over processed may be fragile. Bb.Mending family (Bb.Mending Shampoo, Conditioner, Masque and Complex) is recommended for use to repair fragile hair until strands feel strengthened before using Concen-straight Smoothing Treatment. If you aren't sure, ask your stylist. Additional considerations: This product contains sulfites. If you are sensitive or allergic, consult a physician prior to use. Expect a noticeable odor: Like many treatments, Concen-straight contains technology that is detectable by smell. Dampness can release a smell for a few days after application. It will disappear completely after several shampoos. You may also experience possible color fade: As with any chemical treatment, this treatment may cause color fade, especially in redder tones. In order to avoid shift in color, you must use Concen-straight first, and then wait two weeks to have your hair colored.

Questions & Answers for Bumble and bumble Concen-straight Smoothing Treatment

Question
does this product lighten hair at all-?
states it 'open's hair cuticle' to allow product to penetrate. Typically that means a peroxide which, lightens natural hair color. Anyone out there know? I don't color my hair and do NOT want a change in tone. Thanks!

It lightened my hair, highlights and all-over-color, about one full shade. Package insert cautions that it may lighten red tones, however my hair is dark brown with caramel pieces. Awful product, would not recommend.

I had subtle highlights which were turned orange after this treatment. My hair is very kinky now, not wavy, and I cannot go without blowdrying it. It looks like it was chemically relaxed and very unhealthy.

No, it will wash out of your hair much faster because of all the sodium. Ocean water also isn't good for the treatment. I hate to say this, but women with keratin treatments who swim always use those rubber swim caps-they might be ugly, but they do protect your hair.

Hi There! I swim in both ocean and chlorine water and after applying Concern-Straight Smoothing Treatment, my hair was brassy and weak. After going to the pool or beach, my hair was hard to comb (And I never had problems to comb my hair when wet before) and when letting it naturally dry, it was really frizzy and wild so please think twice before using this product.

It shouldn't, but it will shorten the length of time it continues to be effective. It is good for up to 30 shampoos.....so a dip wouldn't be a hugely detrimental, but I would wear a swimming cap. After the process you go through, I doubt you want to compromise the results.
Hope that helps!

Depending on the condition of your hair from the swimming you've already done, considering how heavily chlorinated the pool is, how many days & for how long you swim for, your hair's texture fine, thick, etc., I WOULD NOT use this treatment on your hair, as all the swimming will cause it to lose its' effect/not hold up, dry your hair out, make it frizzy or break off.

If I were you (Just my opinion) I'd use a good clarifying shampoo 1-2x a week, such as B&B Sunday Shampoo, a good moisturizing masque (B&B Deeep, Creme de Coco, or Thirsty or Mending masque from their Wear and Care line, etc). On days you want to straighten your hair, use B&B Straight Shampoo & Conditioner, then use Blow Dry, section your hair, dry it w/large round brush and use a flattening iron on days you want super straight hair.

For Everyone: A Bumble and Bumble trained hair stylist advised me those with fine/thin textured hair, maturing hair, highlighted, color treated or any other chemically processed hair should NOT use this product, as it MOST LIKELY WILL cause your hair to break off.

If you're unsure if you should use it, I recommend going to a salon that carries B&B and get a trained stylist's recommendation as to if you should use it or not. Otherwise proceed at your own risk!

As an add on to the second review posted from the same person, I could not agree more; I want to shout from the rooftops to everyone I can, NOT to even think of getting this done. I was stupid and even though I saw mostly negative reviews I let a salon convince me that the reviews were inaccurate and that they had only happy customers with this service. I was clear that all I wanted was to defrizz and instead what I got was a 1985 perm solution that ravaged my hair, removed all my curl so I now cannot wash and go and HAVE to actually spend about an hour styling my hair which damages it more. My hair is more frizzy now because what was once just my hair texture is now frizz from hundreds of broken hairs sticking out. My hair is totally wrecked and looks more frizzy than ever while being lifeless and limp. Honestly, just read every negative review out there and disregard the positive ones because I really don’t even believe them. ALL this is is a relaxer done by perm solution that dries the F out of one’s hair and so you’re not really curly or straight so you have to style your hair now with more products than if you’d just left the original texture of your hair stay but use products to mask it. The whole GD point was to have it smoothed; if I wanted to add more products to all the products I was already using then this was the right move. This is a one-way ticket to destroying your hair, stealing it’s moisture, breaking it, taking the life out of it, and looking like a train wreck. I cannot believe salons are selling this garbage to people. WORST thing I’ve ever done to my hair, and I wished I’d trusted the reviews and not the salon. I’m devastated and disgusted and am basically going to cut as much of it out as I can, keep washing it hoping something close to my previous texture ever returns (this texture is literally like cardboard that won’t absorb any conditioner) and I’m going to have to get extensions now in order to look half way decent and grow it back out. Never ever ever will I use a bumble and bumble product after this; I am completely boycotting them.

This sounds a lot like the brazillian blowout treatment, but in a less concentrated form, so I would suggest (if you really didn't want to use the bumble and bumble straight shampoo) to use a shampoo/conditioner that is sulfate free!

l'oreal makes really good ones.

I would think long and hard about using this product on color-treated hair. I used it two weeks after a color and followed the instructions to the letter as my colorist doesn't come cheap.

This product completely bleached my hair out and faded the red, it's now sort of a slightly reddish dishwater blonde -- not hideous, but not by any stretch the color I spent $125 to get. I know reds are prone to fading, but this product really did a number on it.

I won't buy it again for this reason, and I'll definitely let my colorist know what happened.

The instructions say that you need to leave a gap of two weeks between this treatment and coloring you hair. I use only a amonia free, semi permanent color and waited only a week. My hair still feels super healthy. But the product does have a strong chemical smell, so it might be too much for hair that is bleached.

no, i was worried about that as well, especially as it felt a little dry the first time i blow-dried it with the treatment in. After a couple shampoos it is totally back to normal. I think this product is probably the best-quality treatment you can get for your hair.

I have really healthy hair also. I only color my hair every 3 months, and it is with an amonia free, semi permant color. Thisproduct had a strong chemical smell, so it is a process for you hair. I honestly did not see any difference in texture. My hair looks exactly the same, only that it now takes me 3 minutes to blow dry straight. I don't even use a brush anymore while blowdrying!!!

Do the straightened first....it changed the color of my hair slightly. It got a bit lighter. It says to wait two weeks after using the product to do your color. I would say that is being extra safe....probably 10-12 days after would be fine.

I am white, but also have curly, coarse hair and I found this product did little-to-nothing to change my texture. It did not do any damage, but also imparted no benefits (other than slightly reducing frizz for one or two washes), so at best I would avoid it because it will not improve your texture. Good luck!
