Why Use Our Purifying & Deodorizing Shampoo with Japanese Persimmon?

 If searching for the perfect shampoo is wrong, we don’t want to be right! Shampoo is the first step in a quality hair-care routine, so it’s important to find one that will set you up for success. Our Hair Shampoo is the only shampoo in the U.S. with Japanese Persimmon Extract, an amazing ingredient that helps eliminate hair & scalp odor, including the dreaded Nonenal aging odor. Gently cleanse and provide long-lasting nourishment with this restorative shampoo to your beautiful locks of hair.


Why do Old People Smell and What is Nonenal (Aging) Odor?

Nonenal (or 2-Nonenal) was first identified in 2001 by the Japanese cosmetics company Shiseido as the main source of aging body odor. Further studies were documented in a March 2010 issue of the Journal of Biological Chemistry: “Lipid peroxidation generates body odor component trans-2-nonenal covalently bound to protein in vivo.” Nonenal is produced when lipid acids are oxidized (lipid acids are fatty acids produced in sebaceous glands). Hormonal imbalances often result in higher production of lipids. As the skin matures, its natural antioxidant protection decreases, resulting in greater amounts of oxidized lipids.

Nonenal can be recognized by an unpleasant, grassy or greasy odor. It is often hard to detect on oneself but will linger on fabrics, such as shirt collars and pillowcases, if not removed during baths. Nonenal odor often persists in confined environments, such as nursing homes, and is thus sometimes referred to as the old people smell. Because this odor is oil (fatty acid) based, it is not easily removed by conventional soaps and water.

Nonenal’s effect can be different in men and women. Many women experience changes in body odor during menopause. This new odor can be a combination of both increased sweat-based odor and nonenal-based odor, leading to confusion and frustration when these odors are not easily eliminated. Hot flashes and night sweats during menopause cause excessive perspiration and increased fatty acids, resulting in higher production of nonenal. A recent Swedish study showed that middle aged men often have the worst body odor amongst all age groups in males. They hypothesize that this could be due to higher testosterone ratios and related nonenal production. Finally, stress can also exacerbate the production of nonenal in both women and men.

What is Japanese Persimmon and How Does it Remove Odors?

Nature’s Own Purifying and Deodorizing Agent – Japanese Persimmon - is a potent antioxidant loaded with vitamins that has been traditionally used in Japan for its naturally purifying and deodorizing powers. This prized, all-natural ingredient is particularly effective in eliminating Nonenal, the source of that disliked aging body odor or hormonal imbalance odors. Once you use anything with Persimmon Extract, you will feel squeaky clean and refreshingly hydrated. 

Beware though, not all Persimmon Extracts are alike. Persimmon juice obtained manually from the fruit does not eliminate Nonenal odor effectively. Only Japanese Persimmon Extract that is selectively harvested, carefully processed, and tested for maximum deodorizing benefits demonstrates effective results. Mirai Clinical’s Persimmon Extract is harvested each Autumn, processed, and tested in our facilities in Japan under strict Good Manufacturing Practices (GMP). 

This chart shows how Mirai’s Persimmon Tannin is significantly more effective in reducing various causes of bodily odors, including Nonenal, than regular hair care products.

Do I Really Need To Shampoo?

Yes! Over-washing is indeed harsh on your strands, but, as some experts say, depending on your hair texture/type, there actually can be such a thing as going too long between suds. Without regular shampooing, hair can become lackluster, smelly, and worse!

Sebum, which is nature’s hair conditioner, is constantly secreted out of the scalp and onto the hair. It will build up without washing. This can leave the hair looking and feeling quite oil, but worse still, this sebum can act as a food source for bacteria whose action can lead to dandruff (or cause hair loss in some cases). In addition, build-up from other products can collectively dull the hair and weigh it down. A good cleaning with a good shampoo will help alleviate all these issues.

For some people, they claim the no shampoo lifestyle has done wonders, but for others (such as those with very fine hair and/or oily scalps), shampooing can be a necessity. Of course, it is always important to follow what you think is right and do what is best for your hair. You can be rest assured that our Japanese Persimmon Shampoo will not cause further damage to your already precious hair and will provide a nutrient-powered, refreshing cleanse.

Can I Use Soap Bar In Place of Shampoo?

Yes, you can! Both options are safe enough for the scalp and hair, but our Shampoo is specifically formulated to cleanse the hair and scalp thoroughly, so we highly recommend trying it out a few times over the course of a couple months (as you must with any new product).
