Frequently Asked Questions

What is the Kenna Stimulating Hair Tonic?

Kenna's Stimulating Scalp Tonic is an effective, safe, and unique combination of 19 natural ingredients and essential oils, developed by scientists and researchers specializing in hair loss.

How does the product work?

Kenna's Stimulating Scalp Tonic's 19 natural ingredients and essential oils increase the nutrition and blood circulation of the scalp, which aid in the activation of hair follicles' dermal papilla and promote stimulation of hair growth when used as directed.

How long will it take before I can see results?

Consistently using Kenna's Stimulating Scalp Tonic, twice a day, along with maintaining a good personal hygiene routine and an overall commitment to a healthier lifestyle, should produce significant results within just three months after the first use. Results may vary from person to person.

Can Kenna help with hereditary hair loss?

Male Pattern Hair Loss, also known as hereditary hair loss, can affect more than fifty percent of the male population. Treatments vary, from hair replacement surgery to prescription drugs, or a variety of untested and experimental therapies. Kenna's Stimulating Scalp Tonic is a nearly all-natural solution that targets seemingly closed hair follicles and nourishes new hair strands while promoting new hair growth.

Does Kenna directly address DHT?

Dihydrotestosterone (DHT) is a hormone usually found in cases of genetically inherited hair loss. DHT causes the hair follicles to shrink or miniaturize and eventually produce thinner hair. Kenna does not have any direct effect on DHT itself but may help continuously nourish the hair follicles, increase the blood circulation of the scalp, activate dermal papilla to stimulate new hair growth and prevent further thinning of hair.

Can Kenna help with gray hair?

Kenna's Stimulating Scalp Tonic may help address premature graying concerns when used for an extended period of time, because it contains natural ingredients such as Biotin, Phyllanthus Emblica (Indian Gooseberry) and Dexpanthenol (Vitamin B5). These are important ingredients used to maintain natural color and delay the aging process.
