Hair Signals from the makers of Folligen

Is a Solution for:
Thinning Hair & Shedding
March 10, 2010 Reviewed by Marta 2 Comments
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 under $18, 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 and I have just bought myself the Hair Signals Therapy Cream for $27 (we now have Therapy Cream in the TIA shop as well as the Therapy Solution ($38) .

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.


Water, aloe vera gel, copper peptides (soy protein peptides and cupric chloride), octyl palmitate, squalane, crodamol PMP, stearic acid, PEG 100 strearate, glycerol monostearate cetyl alcohol, extra virgin olive oil, germaben II-E, tea extract, beta-sitosterol, saw palmetto oil, lavender oil, pygeum africanum, leucine, polysorbate 80, allantoin, vitamin E TPGS, retinyl palmitate, vitamin E isomers, tocotrienol isomers, coenzyme Q10, leutin, lycopene.

    Hair Signals will help - compared to Folligen it is a bit easier to use and slightly more effective. ReLuma Hair is good, but more expensive. I've used all of these on my brows to good effect and continue with ReLuma

    How does the Hair Signals cream compare to the original Folligen? I want it primarily for my eyebrows, which are very thin. The hair grew back over time, but my hair follicles were so small that the hair is thin and has barely any pigment. I need something that will thicken the hair and make it darker. Will this help? If not this, what would work best?
