I want you to enjoy a beautiful hairstyle for a long time with home care after perm and color.
 
Did you know that shampooing at home after perm color is the most important thing for your hair?
Perm color is like plastic surgery for hair to create a hairstyle. Therefore, depending on the care after the procedure, the reproducibility and sustainability of the hair texture and hairstyle will be affected.
 
For 3 days until the condition of the hair stabilizes, "outflow of hair components and pigments" and "damage by alkali" are likely to progress, and the fading speed is 5 times. In addition, due to the influence of the treatment, the moisture of the scalp decreases, and the barrier function is reduced by about 10%.
 
In addition, the hair color continues to develop even after the treatment, and in fact, it is still about 60% colored at the time of coloring at the beauty salon. The color is best developed after one week, but the pigment of the colorant that has not yet developed is easily washed off by showering or shampooing at home.
 
The home care of the Interlock series consists of three steps: shampoo, treatment, and moist gel, which fixes coloring and perm, repairs damage caused by the treatment, and leads to moist and shiny hair.
I want you to enjoy your hair that has been cleaned at the beauty salon for as long as possible. With the home care of the Interlock series, you can get your hair to its natural luster and shine.
 
 
 
 
 
What are we doing?
Development of professional products that have been used for more than 15 years for professional use
 
We have been the first in Japan to develop and sell perms and treatments for about 70 years, and we have been developing hair care products that meet the needs of the times for many years.
 
In addition, we are still developing products while inheriting the 10 principles set by the founder, such as "obtaining information and knowledge of stores and salons at all times," "development that is friendly to people and the environment," and "easy to use."
Since hair is washed every day, we develop and sell products such as shampoo that have more than 90% degradability of the ingredients and return to nature.
 
The Interlock Series is a professional post-color perm shampoo and treatment that has been used for over 15 years in professional salons. It has been renewed several times and now contains 13 natural plant-derived ingredients and hair repair ingredients.
 
It contains the long-lasting perm and color ingredient "Hematin" and the damage care ingredient "cationized collagen PPT" at the highest concentration in the industry.
In addition, the new ingredient "Elcalactone" protects the hair to the ends, and the treatment effect is doubled by using the heat of the dryer, trowel, and iron.
 
 
 
Commitment to the product
 
"Nourish Shampoo"
It is a professional "black" shampoo after color perm that has been used for more than 15 years for professional use. It is fresh and refreshing, with a gentle scent with a slight sweetness.
 
The black color is due to the compounding ingredient "hematin". You can enjoy a beautiful design for a long time by developing the pigment of the color agent that has not yet developed and fixing it firmly in the hair.
This product is especially recommended for those who have had hair coloring or perming.
It also has the function of removing active oxygen, so it prevents aging and hair loss, and has the effect of keeping hair youthful.
Pre-wash thoroughly with hot water, lather thoroughly, shampoo, leave for 2~3 minutes, and then rinse gently.
 
"Cream PPT Treatment"
It is a treatment that has been sold for commercial use while being renewed several times for more than 20 years since its release.
 
Since PPT components are made up to repair the proteins that make up 88% of hair, the more you use it, the more the protein inside the hair is replenished and moisture is stored in the hair.
Even a small amount of moisturized shiny hair and styling products can be set, making it easy to handle even clean hair.
After shampooing, rub an appropriate amount into the moistened hair. * It is more effective to leave it for 2~3 minutes.
Then rinse gently.
 
 
Who are supporting us?
It is available at more than 100 hair salons.
Many individual customers purchase hair coloring, perm care, and post-hair straightening care at a reasonable price, and those who are looking for full-fledged beauty exclusive products.
 
We have received the following comments from our customers.
 
・Washing softens the hair. Since I started using this shampoo, my wavy hair has gotten better.
・ After drying, it becomes smooth and shiny, and the hair straightening lasts well.
・ The foam is good, and the texture is fine and feels good! Above all, I like the scent of this series.
