Does Priorin Liquid really help with hair loss?

Let’s face it, very few people would sniff at the chance to have some more hair on their head. With this in mind, I tried to find out whether Priorin Liquid, a herbal remedy for hair loss, could be the solution to thinning locks. The results were astonishing.
Fortunately, severe hair loss isn’t something I have to deal with. Now that I’m over 40, however, I do admit that my hair doesn’t have the same splendour as it did when I was 20. Honestly, I wouldn’t mind seeing my locks with a tad more volume. So when I was asked if I fancied testing a hair loss remedy, my curiosity was piqued and I said yes. To tell you the truth, I was still sceptical – as I always am when cosmetic products are touted as miracle workers.
How does Priorin Liquid work?
So what’s in this cosmetic product that’s supposed to stop your hair from falling out? The main active ingredient complex is called Baicapil. Heard of it? Nope, neither had I until I started this review. Basically, it’s a mixture of baikal skullcap root, soy and wheat germ extract. It also contains panthenol (pro-vitamin B5), which supposedly nourishes and moisturises your scalp and hair structure. According to the manufacturer, it’s good for your hair roots and stimulates hair growth. There are no independent scientific studies on Priorin Liquid. One thing I’ve criticised about numerous products like it in the past? If there are any efficacy studies at all, they’re usually done by the companies wanting to sell the products.
Time to apply it and wait for the results
Okay, that’s enough doubt for now. It’s time for my (admittedly subjective) real-world test. This involves applying five to eight sprays of the liquid to my scalp every day and gently rubbing it in. Initially, it’s hard to imagine this would make any difference. For the first few days, it doesn’t feel as if I’m wetting my whole scalp. However, as time goes by and I get some practice at applying the liquid, I manage to do a more comprehensive job of massaging it in. One bottle lasts for about six weeks.
A unexpected result
Then, something unexpected happens. After using the liquid for about two weeks, there’s significantly less hair caught in my hairbrush. When I wear my hair up, my ponytail feels fuller too. Over time, it seems to be getting slightly softer and shinier. There genuinely has been a change. To be honest, the sceptic in me is astounded. Is it just the placebo effect? Well, no. I went into the test so sceptical that I was almost reluctant to notice any impact.
Several months later
I’ve now been using Priorin Liquid for several months. After a few weeks, I did start to get a little lax with applying it. But although I no longer use it every day, I’ve still noticed an improvement. As much as I’d like to confirm this subjective opinion in some way, the series of photos I’ve taken isn’t exactly enlightening. Just like my failed attempt at counting hairs, I simply didn’t have the patience to do it justice. In any case, one person’s experience isn’t enough to make a robust judgement anyway. All we’ve got to go on here is a noticeably hairless brush and the impression that I have fuller, healthier hair.
Now, I’m faced with the same problem that made me wary of the liquid in the first place. The product’s effect only lasts if you continue to use it. Mind you, the same thing applies to medical products. So, that just leaves one question. Is the result worth the investment (and admittedly low effort)? The honest answer is, I don’t know. It might be. And that’s saying something coming from a cosmetics minimalist like me.
In a nutshell
A cosmetic solution for thinning hair
After a few weeks of using Priorin Liquid, I’d say my hair feels fuller, softer and shinier. It’s unclear whether I actually have «more» hair now, but I personally see a noticeable improvement. Priorin Liquid is quick and straightforward to use. The thing is, the product loses its effect once you stop using it. So if you want to give your hair some long-term oomph, you’ll have to keep on applying it.
