Fundamentally, it has become a main thing when customers are going for specific hair services, and not requiring it to match with their lifestyles. However, it is ultimately expected of the stylists to recommend something pretty yet lasting. Think about it from that point of view. The appearance timeframe of beautiful hair, and the time it can stay beautiful; we call it an expiration date. Colour is mainly divided into 3 categories:

「fashion colour」,「(covering) grey hair」, and「bleach colour」.


What’s the interval between (dyeing) fashion colour*?

*fashion colour in Japanese is classified as dyeing the hair to make it a different hue and/or shade or tone


The entire hair length looks twice as long as the grown out roots!


Despite the difference in roots growth varying with each person, a duration of approximately 1 month is usually referred to as 1 cm~1.5 cm (of growth). Following that guideline, it will be about 3 cm in 2 months. When we refer to it as 3 cm, it is considered as measuring across a total of 6 cm when viewed from the top hair parting with both parts/sides visible. Visualising having 6 cm of dark hair (compared to the previously coloured hair), it is quite noticeable, right? Therefore, taking into consideration just the roots growth, we can use 1.5 months as a guideline (The same can be considered for covering grey hair). Regarding the lasting strength (of colour) on the hair, depending on the colour dyed and lightness of the shade, the colour will fade after a month and half or so.


Ensuring it will not result in a brassy hue even after the colour fades…


Fundamentally speaking, the colour gets rinsed out each time you shampoo your hair. After an estimated 50 hair washes in 1.5 months, it is possible for the hair colour to revert back to the shade it was before dyeing. Even so, it is characteristic for Asian hair to fade to a brassy hue. Often disliked by many. Given the above problem, we have come up with two suggestions.


Suggestion 1: Full head colour in cycles of 1.5~2 months


With each time, accumulative usage of the same colour hue (dye) will increase the quality of the colour. Dyeing over the residual colour with the same hue as before will improve the effect of dyeing, as well as enhance the colour’s lasting strength. In other words repeatedly doing full head colour, using the same hue of dye over a short period of time will bring out the colour more prominently along with longer lasting hair colour. Especially when it comes to Asian hair types that fade easily, proceeding with this method will assuredly result in a beautiful hair colour.


Suggestion 2: Retouching the roots after 1.5 months, and then proceeding to dye full head colour again within 3 months. This method establishes a foundation which provides for no gaps in between each appointment. Thus,


also preventing the overall look of the hair from turning into a ‘pudding’ head* (dark roots, light hair). Alternatively, the next time to dye (after a full head colour) can be set around 2.5 months later. By then, the colour would have faded to a certain extent. The benefit of this being that it will be easier to transit to and enjoy a new hair colour.

* ‘pudding’ head (プリン頭) is often used in Japan in reference to a dessert pudding that has a brown caramel top layer, and significantly larger yellow pudding layer

Despite wanting to change your hair colour, it is not going well due to the remaining colour impeding the new colour molecules from absorbing into the hair. Suggestion 2 will be best for people who enjoy experimenting with new hair colours.

What is the interval between (covering) grey hair?

The trick is in treating the grown section of grey/white roots with great care!

The mixture base for this is basically the same as fashion colour. Yet, the issue of concern for both of them are different. Fashion colour targets the newly grown dark roots, whereas (covering) grey hair targets newly grown white/grey roots. In this situation, Suggestion 2 is a good solution as well. However, you may consider a different option.

Suggestion 3: Retouching the roots (with dye formulated to cover grey hair) + dyeing the rest of the hair with fashion colour (formulated dye).

The reason being that the chemicals in the dye (for grey coverage) are formulated to easily darken the hair. Consequently, using it for full head colour will cause the shade to get darker and darker with each application.

Targeting only the roots with the grey coverage, and sparing the rest of the hair with fashion colour, we can prevent that from happening. A lighter shade can be maintained without it darkening eventually. Extending from Suggestion 3, highlights can be inserted to enhance the overall brightness. Making even the usual grey hair coverage an enjoyable colouring experience. This suggestion is even effective for people with sparse grey hairs. Let it be known that grey coverage does not equal dark (hair colour).


What is the interval between bleaching?

With regards to bleach, it varies depending on the design etc. Here we will focus on the scenario whereby the hair is bleached from the roots to tips and then full head colour is applied. In this situation, the interval varies for whether the faded hair will be dyed fully without retouching the roots, or whether the dark roots are bleached again to blend it with the current hair. The interval is mainly based on the time frame from when the colour fades out, to when the colour is applied again. Vibrant colours can be achieved with bleach. The downside being that the colour cannot last for long. That being said, let us introduce our recommended suggestions for bleaching hair.

Suggestion 4: Periodically dyeing full head colour every 3 weeks~1 month


Is it okay to dye your hair at that pace? We get many questions like that but it is definitely alright. Whether it is bleach or regular hair dye, according to the existing damage at the time, the colour mixture can be altered to minimise the damage as much as possible. For hair that is damaged significantly, it is actually easier for colour absorption. Dependent on the colour mixture altered for damage control, it not only helps to minimise damage, it also affects the resulting colour’s vibrance and lasting strength. Besides that, as mentioned previously when the colour has faded, the hair condition will look significantly more damaged. For the next suggestion, it will be for those who want to maintain their bleached hair. How long will it take before the dark roots need to be bleached?

Suggestion 5: Doing full head colour after 3 weeks from the first bleach and dye → Bleach the roots and full head colour again 1 month later


It is typically in a cycle of 1 month for each time of “full head colour →bleach roots + full head colour→full head colour”

If it’s more than a month, the dark roots will have grown out too much and the bleached area + colour would have faded significantly. Therefore making it hard to blend the sections and causing the overall colour to be uneven.

However, it may not be necessary to bleach that often if the specific style does not require it. It is best to discuss in detail with the stylist regarding plans for 2-3 months ahead. For example, designs that are fine with the roots being darker; gradation colours (balayage, ombré). Such designs do not require frequent bleaching and spare the roots from constant damage. For those who don’t mind the ‘pudding’ head roots and bleached hair, pregnant women, or even customers who cannot commit to regular appointments due to work and child- rearing commitments, gradation colour is definitely recommended!

In the end, which is the better option? Full head colour each time, or just the roots?

Before revealing the outcome, we would like to humbly state that compared to dyeing just the roots, the option that gives the best appearance is dyeing full head colour each time. You may be thinking “why is there such a question emerging in the first place?”, but it is likely due to worries with regards to the damage caused.

Mythbusting once and for all, even if it is dyeing the whole head or just the roots, there will most certainly be damage. There is no such thing as “zero damage” be it organic colouring, or periodically dyeing just the roots. This is different in the case of acid colour, hair manicure, or colour treatment products as these do not target the inside of the hair strand but instead coating the outside of the strand with colour. “If that’s the case then wouldn’t just retouching be better?” Dyeing the newly grown roots instead of accumulating the damage all over each time would be better at controlling the damage, no? That is exactly the case. However, the reason for dyeing full head colour is to prevent it from looking damaged! You may be wondering why this is so. Aforementioned, the majority of Asians’ hair quality tends to fade to a brassy hue. It results in the hair colour appearing damaged! Applying chemicals on to hair will naturally cause damage to it. But bearing that in mind, full head colour will reduce the appearance of it being damaged, as well as maintaining the colour consistency of the hair.

Based on that, there are many benefits to doing full head colour each time. Also, depending on the current hair condition and carefully observing it, the roots may not have to be bleached and the colour mixtures can be altered accordingly. The right mixture of chemicals that are best for minimising the damage on each person’s unique hair type and condition are up to the discretion of the stylists after careful diagnosis. The recent colour dyes are so advanced, such that even after dyeing they can improve the overall feel of the hair, adding shine and after-treatment softness. The colour on dyed hair will eventually fade, and there are currently no products that cause zero damage. Despite that, we are still able to achieve that momentary beauty to feel more like our true selves. Do you feel that way too?

どのくらいの期間でカラーすればいいの? 美容師の立場から「美しく髪が見られる」為のポイントをお伝えします! 基本的にはお客様のライフスタイルに合わせて無理なくということが大前提と なってきます。なのであくまで美容師としてオススメするキレイな状態を保つ にはという観点から考えます。美しく見られる期間、美しくいられる期間のことを、賞美期限と私たちは呼びます。 まずカラーのには、大きく分けて

「ファッションカラー」「白髪染め」 「ブリーチカラー」の3種類に分類できます。

ファッションカラーの間隔は? トップの部分は、伸びた長さの倍みえてしまいます! まずおおよそ1カ月で伸びる長さが個人差にもよりますが、1cm~1.5cmと言わ れています。そうすると2カ月で3cm程になるわけです。3cm伸びていると言う ことは、トップの分け目は根元が両側分見えるので6cm空いてるように見 えてしまいます。6cmも黒い所があると思うとけっこう目立ちますよね。なので伸びた根元のこ とだけを考えても、1カ月半位が目安になります。(これは白髪染めにもいえる ことです。)毛先の色の持ちに関しては染めた色や明るさにもよりますが1カ月 半後には色が落ちてしまいます。 色が抜けてしまってオレンジ調になってしまわないように・・・

基本的にシャンプーするたびに色は流れていってしまうので、1カ月半で約50 回程度シャンプーした頃には、染める前くらいにまで戻ってしまう可能性はあ りますね。 そしてアジアン人の多くは抜けるとオレンジっぽくなるのも特徴で、この色合 いが嫌だと言う方はとても多いです。 そこで、提案を2つ考えました。 提案1:周期としては今日染めてから1カ月半から2カ月ご とに全体染め 毎回同じ系統でのカラーを積み重ねて染めることでクオリティを上げて いくことができます。これはどういうことかというと、前回の色があるていど 残っている状態に前回と同じ系統の色合いのカラーをした方が色の染まり具合 も良いですし色持ちも良くなります。 つまり短期間のあいだに毎回全体染めを繰り返していく方が色がキレイ に出るし色持ちも良くなっていくわけです。 特にアッシュ系なんかの抜けやすい色はこの方法で染めていくととてもキレイ に色が出るようになってきます。 提案2:今日染めてから1カ月半後に根元だけ染めて3カ月以内に全体 染めの交互で染めていく今回のカラーから次回のカラーまで空きす ぎないので、常にプリンの状態でなくいられますよね。また、2カ 月半に1回の全体染めなら前回の色が抜けきるので逆に次の色に移 行しやすく、カラーが楽しめるのがメリット。 前回の色が残っているとそれが邪魔になってしまい色を変えたいのに、うまく 色が入らない場合があったりします。なのでいろいろな色を楽しみたいという 方は提案2をオススメします。

白髪染めの間隔は? 伸びてきた「白い部分」を上手に手当していくことが、ポイント! 基本的にベースはファッションカラーと同じです。ただファッションカラーと 白髪染めとでは気になるポイントが違いますよね。 ファッションカラーは新しく伸びてきた黒いところが気になるのに対して白髪 染めは、新しく伸びてきた白髪が気になるということ。 この場合は先ほどの提案2でも良いのですがあえて違う選択をオススメしま す。 提案3:1カ月に1回根元染め+毛先はファッションカラーで 全体染める。。これはどういうことかと言うと、白髪染め はやはり暗くなりやすいカラー剤です。なので白髪染めで 全体を染めてしまうと、どんどん暗くなっていってしまい ます。 そうならないように、根元は白髪染めで毛先はファッションカラーというよう に染めていくと毛先は暗くならずに明るく保つことが可能です。 提案3に捕捉でハイライトを入れてさらに明るく、白髪染めでも十分カラーを 楽しめる まだまだ白髪がまばらに生えてきてる方はこういったやり方が有効になりま す。白髪染め=暗い、というわけではありません。白髪染めでも楽しんでいきましょう

ブリーチの間隔は? ブリーチに関してはどんなデザインかにもよりますが今回は根元から毛先まで 全体的にブリーチをしていてしっかり全体に色を入れているとしましょう。 その場合色が抜けて全体を染める間隔と、根元の黒いところが伸びてきて再度 ブリーチをして繋げる間隔と別になってきます。

まずはやはり全体的に色が抜けてまた色を入れるまでの間隔ですね。ブリーチ はとてもキレイな色が出せる反面、色持ちはあまりよくないのが特徴です。な ので僕のオススメプランはコチラ。 提案4:周期としては今日染めてから3週間〜から1カ月 ごとに全体染め そんなペースで染めて大丈夫?と、よく聞かれますが大丈夫です。 ブリーチであろうと、普通のカラーであろうとその時のダメージによって、カ ラーの配合を変えるのでダメージは最小限に抑えられます。 すでにダメージが強い状態であれば、カラーの色も入りやすい状態なので、ダ メージを抑えた配合にすることによって、ダメージの低減だけでなく仕上がり のキレイさや、色持ちにも良い影響を与えてくれます。 それよりも先ほど伝えたように色が抜けた状態の方がよほど傷んで見えてしま います。 では、ブリーチのスタイルを維持していきたい場合根元の黒い所をブリーチす るにはどれくらいの間隔かというと。 提案5:今日染めてから3週間後に全体カラー→そこか ら1カ月後に根元のブリーチと全体カラー 全体カラー→ブリーチ+全体カラー→全体カラーというループを基本は1 カ月の周期で。 それ以上空くと黒いところが伸び過ぎてしまうと、すでにブリーチしてある明 るいところと、上手く繋がりにくくなってしまいムラになりやすくなってきま す。 ただやりたいスタイルによってはブリーチを継続していく必要のない場合もあ るので、担当美容師としっかりと2、3カ月ごとのプランを話しておきましょ う。 例えば根元暗めで大丈夫なグラデーションカラー(バレイアージュ、オンブレ)

のようなデザインであれば地毛を活かせるのでブリーチを繰り返していく必要 はありません。 なので、根元のプリンをあまり気にしたくないという方や、妊婦さんやどうし ても仕事や子育てで頻繁に来れないという方はグラデーションカラーが絶対的 におススメです! 結局毎回全体染めるのと根元だけ染めるのどっちが いいの? 結果から先に申しあげますと毎回全体染めの方が見た目としてはキレイに 見えますし、まとまりなんかもよくなったりするので根元だけ染めるよりも全 体染めを繰り返す方がキレイに見せることができます。 そもそも何でそんな疑問が生まれるか?ですがやはりみなさんダメージを気に して、ということだと思います。 ずばり!カラーをすれば全体でも根元染めでも必ずダメージはありま す。 オーガニックカラーだからダメージを全くしないとか、根元だけ繰り返してた らダメージしないなんてことはありません。髪の内部に入らず外側に色をコー ティングするようなマニキュアやカラートリートメント、アシッドカラーは別 ですが ならリタッチだけの方が良くない?ってなりますよね?ダメージが蓄積してい くよりは毎回新しく生えたところに染めた方が傷みは抑えられますからね。そ れはその通りです。しかし実は、傷んで見えないのは毎回全体染めするこ とです! どういうことかというと、先ほど言ったようにアジアン人の髪質的に多くの方 は染めた色が抜けるとオレンジっぽく色落ちします。そうやって抜けた色合い は傷んで見えやすい状態の色なんです! 髪に薬剤をつければもちろんダメージはありますが、それを差し引いてもしっ かり全体を染めた方が見た目としては傷んで見えないし、毛先のまとまりなんかもよくなったりします。

そういったことを踏まえて毎回全体染めする方が結果的にメリットがたくさん あるという訳です。 あとは、髪の毛の状態をしっかり見てダメージが強いところには負担が軽い配 合、根元の黒くしっかり明るくしなければならないところは通常のカラーの配 合を。 と、いった具合で美容師がきちんと毛髪診断をして適材適所に薬剤を使う ことでダメージを最小限に抑えることができます。 最近のカラー剤はとても優秀でむしろ染めた方が手触りが良くなったり、ツヤ 感もトリートメントしたかのように出たりします。 カラーは必ず色落ちもしますし、傷まないカラーは今のところありません。し かし定期的にお手入れをしていくことでよりキレイにあなたらしくいられるこ とができるじゃないでしょうか?
