Used for 5 months, then again after 4 months. Here’s my review.Used it for 5 months from February to July:I’m a woman at 31, with short to medium-length hair. Everyone wants to know if it works first, and the answer is YES! I started using this in February 2018 to grow some of my hair back. By March, I started noticing that my hair was growing out a little bit thicker. In April, I took a trip to Singapore and Japan, and continued to use this religiously every morning while I was there. Singapore was really hot and humid, by the way, so using this made me feel a bit heavy, but I had gotten used to it. By this time, my bald spot wasn’t apparent anymore. Having a head full of hair without any glares from the top of my skull made me feel more confident about myself.Promise delivered:My hair fell out a lot less in the shower, and like I said, my bald spots weren’t so visible and apparent anymore. In fact, I no longer noticed them. My roots became super thick as well, my baby hairs around my hairline were growing so beautifully and abundantly that I kept touching it. Another thing is that this product was a little like mouse or wax, so I actually didn’t have to use any other hair products while I was using Rogaine.Allergy to Rogaine developed – the consequences:By July, however, my scalp had started to itch. It itched so badly that I had to stop the Rogaine treatment altogether. This wasn’t due to the weather. I think I developed some kind of allergy to Rogaine because 4 months later in November, I tried to use it again and had the same exact itching reaction by the 2nd day! My head was itchy, the Rogaine came off with my skin in patches… You get the idea. So I can no longer use Rogaine ever again. And no, it had nothing to do with the specific bottle. I had been using the same bottle during the month of July when this allergy suddenly happened. So, I can no longer ever use Rogaine again!What happened after I stopped the Rogaine treatments:So did my hair fall out after I stopped using Rogaine? Well, actually… It didn’t fall out excessively like it used to before I used Rogaine. In fact, for the first month after stopping the Rogaine treatments, my hair stayed almost intact. Very little missing hair, no bald spot… My head and hair wasn’t reverting back to how it used to be, like others said it would when you stop using Rogaine. This stayed like this for an entire month.After a month, my hair did start falling out, but slowly. My hair remained thick. I think it has something to do with the Biotin shampoo I was using once in a while though. Anyways, 4 months later (in November) was when I actually started noticing my bald spot again. Yeah, I was surprised it took 4 months for my hair to fall out instead of immediately after I stopped using Rogaine. Maybe I had changes in my lifestyle? Gosh, I can’t imagine what changed though. I gained more weight I guess…? My biotin shampoo that I occasionally use? I don’t know…Conclusion:Rogaine works. For some, like me, it will work better than for others. However, I developed an allergy to this thing mid-way through it. I itched like crazy for 2 weeks before the inflammation went away. So, while I do recommend it, I just thought I’d let people know that the allergy symptoms are a possible side-effect.How to apply:I recommend looking on any Youtube videos, but basically:- Hair must be dry.- I filled the cap from the rogaine bottle 3/4th full. This is enough for my short to medium-length hair. Sometimes, if I need more, I squeeze about a 5th out into the cap at a time.- I use a fine tooth comb with a pointed end to split my hair. Using a comb that you don’t share with others is ideal for Rogaine so that the product doesn’t transfer to your regular brush.- Split your hair section by section as you apply with your finger little bit at a time.- When done, rinse the cap and the comb, then style your hair as usual.This gets easier and faster as you do it. It first took me 20 minutes each day, but then I got so quick at it that it only takes me 3-5 minutes.
