  • Application challenges
I like the product, but I find it a little difficult to apply. Since I also use the Triphasic Progressive, I transfer the Reactional serum to an empty container and applicator from the Progressive, which is much easier to use. I would suggest they improve the application method.

  • Great so far
Feels soothing yet energizing on my scalp and smells amazing!

  • Stopped hair loss, no growth
Started with the progressive treatment, saw no hair growth. Switched to Reactional and my hair loss just about completely stopped, but again no hair growth.

  • Skeptical if it works
I purchased so many things all at once to help with post partum hair loss and am not 100% certain what’s helped/worked! After spending so much money on this product o realized the second ingredient on this product is alcohol!!! How is this suppose to actually help the hair regrow w alcohol 😩

  • Very drying
I am on my third week I see zero improvement but my hair has gotten really dry. I doubt I can go through it with the whole treatment.

  • Fabulous for Sudden Hair Loss
I’ve had thin, very fine and poker straight hair my entire life as do others in my family so a hair stylist I used 10+ years ago recommended the TRIPHASIC Progressive Concentrated Serum, Hereditary & Hormonal Thinning Hair which I liked very much but it’s expensive so I’d only buy it occasionally but then in May of 2019, I got a urinary tract infection that was so severe that I was hospitalized for 9 days. I had a very high white blood cell count and spiking fevers. It was so bad that I damaged my kidneys. About 2-3 months later, my hair started falling out in near clumps. I went to a dermatologist who diagnosed me with a sudden hair loss condition called “telogen effluvium” which is caused by a “shock” to the system (in my case, the high fever). It’s different from alopecia and usually starts when my did-a couple or 3 months after whatever the “shock” was. I can’t tell you how upsetting it was to just run my fingers through my hair and have a near handful of hair come out. The doctor gave me a prescription liquid corticosteroid which actually didn’t do much. I got my hair cut very short and then googled what to use to help prevent further loss and there were a ton of suggestions but I choose to use this product designed for “reactional and sudden” thinning. The hair loss stopped on it’s own which is typical for the condition but I wanted to treat my scalp and promote hair growth so I started using this product and it worked! I actually now have slightly thicker hair than I ever had and the “texture” is different but that’s likely more from the hair loss in general. But this product very much helped with the overall regrowth. Highly recommend. ... show more

  • SUB PAR
I purchased this product directly from the Rene Futerer website and it worked amazingly well. The product through Amazon is causing my hair to shed terribly! I wonder if this is a legitimate product. Never again!

  • USELESS...sorry
Did not stop my hair loss through the telogen effluvium- my hair loss got worse and is now tapering after 3 months (this is the normal course- not due to the product). I had high hopes initially- but useless against hair loss. The product itself smells nice. The applicator is difficult- I bought a glass eye dropper to apply. ... show more
