I discovered Skin Biology’s Folligen Cream for stimulating hair growth almost two years ago and it remains one of my better finds. It is great for restoring hairlines and helping eyelashes and brows grow. At the bargain price of just $22, it is hardly surprising that it is the runaway bestseller in the Truth In Aging shop. Not long ago, Skin Biology brought out a new product duo called Hair Signals (Cream and Lotion) and I like it even more. For me, Skin Biology Hair Signals Cream Therapy Cream ($24) actually worked even better than Folligen at growing the thinning hair on my hairline! And we are not talking wispy, baby hair. But proper hair.

Hair Signals has the same copper peptides active as Folligen, with a proven track record for growing hair (not to mention healing wounds). But it also has some other ingredients that appear to rally behind the copper peptides to tackle thinning, aging hair.

Dihydrotestosterone (DHT), a natural metabolite in the human body, is responsible for shrinking the hair follicle (think wispy). This is referred to as miniaturization and the hair ultimately breaks and falls off. Men or women who lose hair are those who are genetically pre-disposed in producing more DHT than others.

Ingredients that are thought to inhibit DHT include tea extracts, saw palmetto oil, pygeum africanum, and lavender oil – although only saw palmetto has a strong research pedigree when it comes to hair growth. They are all here in Hair Signals and, with exception of saw palmetto, are not included in the Folligen formula. There are also the antioxidants CoQ10 and lycopene, plus lutein, a carotenid found in leafy greens.

Although at first glance, Hair Signals seems to have eshewed parabens, there are actually two in the ingredient that goes by the name of germaben 11-E. And for the nerdy (or suspicious), crodamol is a chemical and benign emollient ester.

We also have Hair Signals Therapy Solution in the TIA store for $36. This is for an all-over scalp treatment for thinning hair, whilst the Cream is better for targeting specific areas such as the hairline.

    I first tried this product back in 2010 (after reading Marta's review), and was very impressed. My eyelashes had gotten really sparse, and brows were almost gone. My hairline was receding a bit, too ... yikes.

    The Skin Biology Hair Signals Therapy Cream really worked. I used it sparingly on my eyelids (afraid of irritation), but my lashes grew thicker and fuller. New hairline growth appeared within a couple of weeks, too. It darkened my eyebrows, which was fine, but strange, since they've always been blond.

    That first tube lasted over a year, and I literally cut it open and scraped the last bits out when it finally ran out.

    I've just recently ordered it again, and am happy to see tiny little hairs popping out already.

    I highly recommend this product, and should the hair on my head start thinning, I'll order the scalp treatment, too.

    Skin Biology has all product directions on their website. I assume people would read up on a products use before ordering. Re Folligen I found it irritated my eyes also and after diligent use of a couple months noticed no change in my brow hair. So thanks for the info on hair signals being stronger, will try that route.

    Hi Karen

    Skin Biology doesn't provide instructions so we actually wrote our own one-pager. You should have received one with your order if you bought it from us. I'll email it to you.
