The instructions say to go under a dryer for 15 minutes. Do you use a hair dryer at home?
- Asked by Shelly
- Verified Reply - Brand ExpertHi Shelly! That is a great question. Intense RX is a reparative keratin serum that you leave in the hair. Over time it helps to make the hair healthier and stronger from the inside out. For at home use, simply apply this product first so it can penetrate in to the cuticle and then continue to style your hair as you always do. I would recommend using Infusion Keratin Replenisher on top of Intense RX and then blow drying you hair for a smooth and silky result. It is not necessary to place your hair under heat. Those instructions are geared towards stylists in the salon and need to be updated so my apologies. Please let me know if you have any more questions.Was this answer helpful to you

my hair is chemically damaged. How many applications before I see significant results??
- Asked by Dawn
- Verified Reply - Brand ExpertHi Dawn, I am so sorry my response is delayed. Intense RX is an extremely reparative product and after a couple weeks of treating your hair you should most definitely see some results. Your hair will gradually become healthier and stronger from the inside out.Was this answer helpful to you
- Q
How long does the results last?
- Asked by sathya
- Verified Reply - Staff ExpertResults last for about two washes. It is a temporary treatment; however, the more you use Intense RX, the healthier and stronger you hair will become. We recommend using it every 3 washes to receive optimal results. :-)Was this answer helpful to you

AMAZING
This product is by far my favorite hair product that I use!!! I love it even more than my heat diffuser, and hair spray (which is DEFINITELY saying something, LOL). It's super easy to fit into your shower, and hair styling routine, whether you do it at night or in the morning; it makes it SO much ea...

I don't see any benefits
I was very excited to receive this product, I've been using it for a couple of weeks now and it has done absolutely nothing for my hair. Very disappointed since it was expensive. Certainly would not buy again!

HIGH LEVELS OF FORMALDEHYDE
Hair Type Wavy Hair
The intense RX Serum was recalled because it has dangerous levels of formaldehyde and is not legal in the US.
I love this stuff!
Been using this for several years now and it's simply amazing when used as a styling product. I put a small amount in my ends before I hair dry and it makes my hair feel healthy and shiny, but when you wash your hair it'll be back to how it was pre product Doesn't weight hair down, nor does it leave a build up.
Did Nothing
I was so hoping to love this. I'm glad I got it half price when Ulta was doing the hair sale because it honestly did nothing. I thought it might help with dry ends but it did not. Very watery consistency as well. Won't buy again even at half price.
Favorite Hair Product!
I have been using this product before blow drying and my hair has never looked better. My hair was dry and I had a lot of split ends, now it looks a lot healthier and shinier. Best hair product I have ever used.
RX fir split ends
I use this with my infusion to strengthen my ends which are weak from growing iut
