How to Use Japanese Seaweed to Cleanse, Condition and Care for Hair

Japanese way of using Funori is to mix it with hot water

Funori is a traditional Japanese hair cleanser and conditioner made from three seaweeds: fukuro-funori (also known as jelly moss), ma-kombu (edible kombu), and mekabu (nutrient-rich roots of wakame seaweed). It is all-natural and contains no additives, preservatives, colorings or fragrances.

Funori comes in powder form. The Japanese way of using Funori is to mix it with hot water and then apply the mixture to cleanse and condition the hair. You can also apply it as a deep treatment pack or mix it with your shampoo.

How to Control Oily Hair by Preening

Hair's oil glands are in the scalp. As a result, hair is always oilier near the roots and drier towards the ends.

Preening is the process of distributing your hair's natural oils by running your fingers through your hair. All living things with hair, fur, or feathers preen as a matter of instinct (we have all seen birds preen their feathers with their beaks to keep them in good order and looking beautiful).

  1. Massage your scalp until you feel oil on pads of your fingers.
  2. Run your fingers along the length of your hair, untangling and smoothing as you go.
  3. Keep preenig till you feel there is no more oil to spread.
  4. Do it daily, or as often as you feel necessary. 

Regular combing also distributes hair's oil evenly and reduces the "oily" scalp feeling. It polishes the hair strands as well, making it more difficult for dirt particles to stick to the hair shaft, and easier to wash off.

Conditioning and Reducing Hair Loss with Seaweed

Funori is a source of vitamin K, calcium, magnesium, iron, iodine, and Fucoidan polysaccharides. It nourishes the scalp, restores hair’s natural sheen, and makes it more manageable.

There are many reported cases of Funori reducing hair loss and promoting new growth. Below are actual pictures.

Cleansing Hair with Seaweed Instead of Shampoos

When you mix Funori with water, you get a surfactant-free, non-alkaline viscous mixture, with a near-neutral pH of 6.5. Funori cleanses hair by sticking to dirt and pollutants on the hair shaft and rinsing them off, without chemically throwing off the healthy balance of hair's natural oils.

In contrast, shampoos are alkaline. They dissolve hair's oil and rinse it off, along with any dirt on the hair shaft. Shampoos do not discriminate between the "bad" dirt and the "good" hair oil; they strip both. With shampoos, you get "clean, squeaky" hair: Clean, because the dirt is gone, and squeaky, because hair's natural oils are gone too.

Shampoos and Oil Control Myth

The oil glands (sebaceous glands) in healthy scalp have built-in control mechanisms which sense whether scalp and hair are dry or oily, and by how much. If dry, they produce oil to alleviate the dryness. Once there is enough oil, they stop. These control mechanisms are nature's way of keeping a balanced, healthy level of necessary oils.

Shampooing chemically strips hair's oils. Oil glands sense the sudden lack of oil and become over-active. The result is a vicious cycle in which oil glands over-produce, and we feel the need for constant shampooing to "control" oil — where in fact, it is the shampoo which causes the oil glands to over-produce in the first place.

Going Shampoo-free

If you have been using shampoos and conditioners frequently for years, your scalp's oil glands will need to adjust to the new shampoo-free routine.

Depending on the individual, this adjustment period can take a few days to a few weeks during which time hair can feel too dry or too oily. After the adjustment period, hair's oil level stabilizes to its normal state.
