Hairdressing How-To: Putting Foils in Hair—Tips, Tricks, Advice, and Know-How for Colouring Hair with Foils!

Hair Tips and Tricks with Foils

In the hairdressing world, foils are commonly used to add highlights to a client's hair. Very few people other than hair artists know the other amazing uses for foils!

In addition to highlighting, you can lowlight, use foils to dye most of the hair and leave a few bits natural (sort of like the opposite of highlighting), protect sections of hair from becoming over-processed, add in additional streaks that are bleached or colored, or touch up just the roots of color that's growing out. The truth is that hairdressing foil is a very versatile tool and can be used for several different tasks to create an array of interesting looks.

First, I'll tell you the right way to apply foils to the head. Then, I'll explain all the different things you can do once the foils are in, and along the way I'll show you some videos to illustrate the process.

About Foil for Hair (Can I Use Aluminum Foil?)

Yes, you can use regular aluminum foil for your hair, as long as the dye you're using says it's safe with metal. You could even use waxed paper if you wanted, and of course the stuff you buy at a beauty supply store will work too, although it may be more expensive.

Before you begin, you'll want to cut the foil into strips of manageable size, depending on the length of the hair you're working with. Usually, you'll cut strips that are four or five inches (10-13 cm) wide and eight to twelve inches (20-30 cm) long. Because you'll fold it up to encase the hair, cut strips that are about twice the length of the hair you're dyeing. For extremely long hair, instead of folding one piece of impossibly long foil over, you can use two separate pieces of foil that are each the length of the hair as a kind of foil sandwich.

You can use a piece of foil that is less than double the length of the sectioned hair, but the hair will need to be curled or tucked up inside the foil. Be careful while doing this so as not to bend the hair (and leave a visible crease in the dye).

Since foil comes in various strengths and thicknesses, you'll want to consider this, too. The trick is using a material that is tough enough to hold up to the chemicals in the dye, and still malleable enough to keep the sections of dyed hair separate. Another way to make sure your foil will hold up is to fold about an inch of the foil down on the end that will touch the roots of the hair. This will make that end doubly-strong and will help ensure that the dye will be contained.

DIY: How to Put Foils in Hair

Before you start with the foil, you should wash and dry your hair and have everything you need ready and on hand:

  • a clean head of hair,
  • barrettes or clips,
  • the color or bleach you'll be using (mixed, if applicable),
  • a tail comb,
  • a tinting brush for applying the dye, and
  • strips of foil.

Step #1: Sectioning Hair

1. Section off the hair that you wish to color. Dividing that hair into smaller bundles will give you more control over the process. Temporarily secure each section with a hairdressing barrette.

Step #2: Using a Tail Comb

Use the end of the tail comb to select which pieces you will dye. This requires artfully grabbing chunks of the hair or weaving the end of a tail comb through the hair select separate sections. If you're working on a friend's hair, you'll want to start with the sections at the bottom (closer to the neck) and work your way towards the front (forehead). If you're doing your own hair, you'll probably start at the sides and work your way up to the top. For a natural look, large chunks of hair are not recommended: instead, use smaller sections and many separate foils.

Step #3: Using Foil

Place that sturdy, folded end of the foil under the section of hair you're going to apply the dye to, preferably with the silver side facing up (although the foil can be used either way).

Step #4: Applying Dye

Apply the hair colourant that you are using, providing that it is safe to use with metal, with a tinting comb. Make sure to thoroughly coat the hair. Use the foil itself as a sort of canvas or table, as it will provide a little support for the strand of hair you are coating.

Step #5: Using Foil

Make sure the foil is tucked in close to the scalp and covering as much of the roots of the hair as possible to prevent the dye from getting onto other sections of hair. To wrap up the foil, begin by taking the end (opposite the roots) and folding it up over so that the hair is entirely encased in an envelope of foil. Do not press too hard when you fold the foil or you will cause a colour leakage. It will take practice to get this perfect! (Remember, for extra long hair, you can use two separate pieces of foil sandwiched together.)

Use the foil to separate dyed from undyed sections.

Step #6: Folding the Foil

Now, you can fold the foil so that the ends of the foil-encased hair come up close to the roots. Be careful not to press too hard or you'll have a fold-crease in your dye. Don't worry if the foil looks messy at this stage, practice is required to make a perfectly folded foil. If the hair is long, you may wish to gently roll the foil from the bottom upward to the scalp instead of folding.

Step #7: Repeat

7. Repeat steps one through six until you have foiled all the hair you plan on dyeing. If attempting this on your own hair, especially if your hair is long, you may need the help of a friend the first couple of times. For how long to leave the dye in, read the instructions on the bottle. Since this whole procedure is quite is slow, the sections you begin with will be exposed longer to the dye than the ones you do last. To ensure that all your foils are the same colour after the instructed period of time, you may want to section off all the pieces of hair you want dyed first, then quickly work to dye and wrap them up.

What Else Can You Use Foil For?

However, foils aren't only used for dying sections of hair. Here are just a few professional tips and tricks which are extremely handy for DIY, at-home hair colouring sessions.


Foils are most often used if you only want to dye a few bits of your hair. However, if you wish to dye the bulk of your hair and protect a few bits from being processed, foils are also great. You can simply section off the hair you want to keep undyed and wrap each section in foil, using the same procedure described above, only without adding the dye. Then you can proceed to dye the remainder of your loose hair, working carefully around the foils.

DIY: Bleaching Hair with Foils

If parts of your hair are already bleached, but you want to lighten the rest or add more bleached sections, then the exclusion method can also be used. This trick is excellent for protecting hair that has been damaged from over-processing with bleach, in order to avoid excessive damage. If you want to lighten the rest of your hair, the already-bleached parts should be covered and therefore saved from excessive processing. If you choose to bleach already bleach-damaged hair, you may end up with a chemical haircut!

Using Foils for Regrowth Applications (Touch-Ups)

Foils are great to use with regrowth applications if you don't wish to dye over your previously-dyed hair. This is especially true for highlights as overlapping more bleach on top of your previous highlights will lighten your hair further and lead to a slight 'stripey' effect. You can use the exclusion method for this.

Tips for Root Protection

When excluding hair from a process using foils, you may find it hard to cover the roots with the foil, and this may become a cause for worry. One handy piece of equipment in this case is your conditioner! Using your tinting comb, brush some conditioner onto the roots of your hair to prevent them from being processed. You can also apply it to your eyebrows in case the hair you're dying falls in your face!

What do your think about do-it-yourself home dyeing with foils?

  • I did it and it worked great! I'll never need to pay full price again.
  • I tried: I made a bit of a mess, but I'll try again.
  • I tried, but it wasn't worth it. I'd much rather pay the salon.

I've never even considered writing for a hair dressing magazine! Most of the ones which I buy are published in the UK though, and I don't know of any that are published in Australia. Also, they may not take me seriously since I'm not over 29 =] Thankyou for the compliment and good luck to you too.

Very good way of explaining, I still cringe though when I read or hear the word dye instead of colour LOL

Thanks for your comment, momo. To me, the terms dye and colour are interchangeable.

Great job. You seem to really know a lot about the whole hair coloring and styling thing, and you laid it all out so that anyone could easily understand the process you were taking them through. That isn't always the easist thing to do. You definitely have a future in writing and in the hair business.

How do you bleach just the root of previously bleached foils without going over the bleached portion while also avoiding creating a blunt line of older/newer bleach?

VB72 - I always have trouble with this issue myself. Remember - practice always makes perfect! You'll find at most salons for regrowth applications of bleach, a weaker solution is used, with a graduated result. This also helps you to go for longer between salon visits, because there isn't an oobvious line between the lighter and darker hair.

If your foils are bleeding, then you have put too much product in them.

got a foil recently to lighten up my hair...does the sun damage hair after having a foil if I do not wear a hat or avoid the sun? My hair stylist says not to worry about the sun after a foil. Thanks

Jennifer 5 years ago

@ Heather - sun exposure and can damage you hair if it is colored or not. There are products out there to help with protecting your hair. Try Redken's Color Extend SUN line to help protect your hair.

Can you use foil with any home coloring kit, such as Revlon ColorSilk? I'm trying to give my daughter "low lights" and using a cap didn't work because the amount of hair I could pull through wasn't noticeable enough when we finished so I'd like to try foils so I can use larger sections.

I'm a hairdresser also and to avoid the foil from bleeding you can use cotton in between foils so that if it does bleed, the cotton will absorb it before the color touches the hair.
