What Kind of Products Do I Use for Hair Coloring? / International Hairdresser TAKA
I want to offer hair color that naturally enhances each person’s unique individuality—regardless of their nationality, background, or hair type.
To do that, I use a product called “PROMASTER” by the Japanese brand hoyu.
There are three main reasons why I choose this color product.
① Low-alkaline color that causes only 1/10 the damage
PROMASTER includes two types of color: a standard permanent formula and a low-alkaline semi-permanent formula.
The biggest feature of the low-alkaline option is that it reduces damage to about one-tenth compared to regular color products.
Human skin is naturally slightly acidic.
That’s why regular color products, which are alkaline in pH, can put stress on the hair and scalp.
Low-alkaline colors have a pH closer to skin, which helps reduce that damage.
- ✅ Less tingling—great for sensitive or allergy-prone skin
- ✅ Minimal chemical odor after coloring
- ✅ Safe for dry ends, straightened, or permed hair
- ✅ Can dye just the gray hairs without changing your natural hair color (like natural highlights)
The low-alkaline version can’t lighten the hair, but I believe its gentleness and ease of use far outweigh that limitation.
② A color palette that adapts to both trends and skin tones
PROMASTER includes a perfectly balanced set of six base colors—red, orange, yellow, green, blue, and purple.
It’s truly universal, no matter the customer’s nationality or background.
Thanks to this balance, I can offer:
・Personalized tones that match your skin or eyes
・Colors that suit your fashion and lifestyle
・Highlights that bring out your inner beauty—like a custom-made look
It lowers the risk of color failure, and most importantly, gives you more freedom to enjoy color.
③ You can still choose freely—even with gray hair
“With gray hair, you can only go dark.” A lot of people still think this way, but it’s no longer true.
PROMASTER allows full gray coverage while still letting you create vivid shades using its six base colors.
Of course, if your hair has been dyed very dark before, it may take time to gradually lift the tone. But with careful adjustment, you can still enjoy new colors.
“I have gray hair, so I have to settle”—no. I hope you’ll start thinking, “I have gray hair, so I can enjoy more freedom.”
Hair color is just one tool to help people feel happy.
No matter how good the product, what matters most is how the stylist uses it.
That means, “Does my knowledge of the product help me deliver what the client truly wants?”
・Is it right for your hair type?
・Is it safe for your skin?
・Will it cover your gray hair beautifully?
PROMASTER is a product that answers all of these needs.
For anyone who has struggled with hair color in the past, I hope this brings you a sense of relief.
