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.
