Types of Hair Perms: Choosing the Right Style for You

The Ultimate Guide to Hair Perms: Styles & Tips from Kosa Salon SF

Are you dreaming of voluminous curls or soft waves but unsure what hair perm would suit you best? There are so many perm variations in the market, and it can get confusing as every type has its benefits and styles to offer.

People repeatedly try using different variants of hair perms on their hair and need help finding the right fit for their lifestyle. This was one of the main reasons the Kosa Salon SF team started planning their foray into the hair perm market. 

We felt there was a lack of proper guidance for hair perms, and with Kosa Salon, we want to make it easier for our beloved readers to make the right decision and find the perfect perm that suits their hair type and maintains its health without compromise.

What is a Hair Perm?

A hair perm, also known as a permanent wave, is a chemical treatment that disrupts the bonds of your hair to change its structure and create curls. During the process, a perm solution is used to cause the hair to break away from its tight shape. The hair is then wrapped around rods that will give it the new shape it wants, and finally, a neutralizer is used to reset the bonds with the rods in place. 

The final result of the treatment is curls or waves in a style of your choosing that keep their shape and can last up to three months, giving the hair additional volume and texture.

5 Types of Hair Perms – Choose The Best

1. Cold Perm

A cold perm is one of the oldest perming techniques. Also called an alkaline perm, this treatment involves applying an alkaline solution to the hair, which breaks the disulfide bonds of the hair structure. The strands are then wrapped around a rod and fixed into position. Then, a neutralizing solution is sprayed, in which the bonds reform to set the curl.

Unique Features

What sets a cold perm apart is that it generates tighter, more defined curls than a hot perm. This results in longer-lasting permed hair that will remain on trend whatever life throws your way. Most importantly, a cold perm allows you to continue your life uninterrupted because it requires the least daily styling.

Suitable Hair Types

Cold perms are good on a fine to medium hair texture. Very curly hair doesn’t need more curls, but they are ideal for straight or slightly wavy hair that wants a more textured curl.

Pros and Cons

Pros:

  • Long-lasting results
  • Defined, tight curls
  • Suitable for various hair lengths

Cons:

  • It can be dried to the hair
  • Requires proper aftercare to maintain curl definition

2. Digital Perm

A digital perm, a different version of a curling procedure called a hot perm, is produced with digital heat rods and a chemical solution. The rods can be heated to a particular temperature appropriate for curling, adding more definition to the outcome and making the curls look natural.

Unique Features:

A digital perm creates softer, more natural-looking waves and curls than a cold perm because the digital heat pattern creates looser and more voluminous curls. 

Suitable Hair Types

Digital perms work best on coarse and thick hair. They are ideal if you want a more believable wave pattern than a cold perm and prefer a less tight wave.

Pros and Cons

Pros:

  • Natural-looking curls
  • Softer, looser wave pattern
  • Suitable for thicker hair

Cons:

  • It can be more expensive than cold perms
  • It takes longer to complete the process.

3. Body Wave Perm

Body waves are achieved with larger rods that create a looser curl or wave pattern. They are designed to add body, life, and movement to the hair without tight curls.

Unique Features

Unlike the other perm types, body wave perms give soft, natural waves that add body and texture. This makes them popular with those seeking to boost their natural hair while keeping the same length.

Suitable Hair Types

Body wave perms are perfect for thin, flat-textured hair with some volume. They should also work for body types with straight or wavy hair looking for more texture.

Pros and Cons

Pros:

  • Adds volume and movement
  • Creates a natural wave pattern
  • Low-maintenance styling

Cons:

  • It may not last as long as other perm types
  • Less defined curls

4. Spiral Perm

A spiral perm uses many small rods in a vertical wrapping technique, yielding small, springy curls that create a defined, voluminous curl—a look that makes a dramatic statement. 

Unique Features

The spiral perm is an actual curl with an even rotation around its axis called a curl. The curls are even; if appropriately done with a spiral perm, they can last several months.

Suitable Hair Types

The spiral perm works best on long hair, providing lots of length to create the swirling-wave effect. Also, the hair can be moved easily, making lots of bends and the unkempt wave that spiral perms are meant for. 

Pros and Cons

Pros:

  • Creates tight, defined curls
  • Adds significant volume
  • Long-lasting results

Cons:

  • It can be time-consuming to apply
  • Requires diligent aftercare to maintain curl shape

5. Root Perm

A root perm focuses on perming only the roots of the hair, providing lift and volume at the base. This technique is ideal for individuals who want to add fullness to their hair without perming the entire length.

Unique Features

Root perms create a permed texture at the root and boost the crown’s volume, creating the illusion of thicker, fuller hair. They’re also perfect for giving worn-out permed hair a little pick-me-up, refreshing the feel of loose curls.

Suitable Hair Types

They are perfect if your hair is flat and lifeless and needs a bit of lift. They are also ideal for those who want to add fullness without changing what’s left when the rollers are removed.

Pros and Cons

Pros:

  • Adds lift and volume at the roots
  • Less damaging to hair overall
  • Quick application process

Cons:

  • Volume may reduce as hair grows out
  • Not suitable for those seeking full-head curls

Choosing the Right Perm for You

Your hair texture and the regularity of your maintenance routine influence the type of perm best suited for you. However, there is no definite answer, so consulting with reputable hair stylists is always recommended. At Kosa Salon SF, our professional hair stylists can evaluate your hair and recommend the most appropriate type of perm. We guide you to achieve the best results in line with your hair texture while preserving your hair’s look and integrity.

General Perm Aftercare Tips

Proper aftercare is crucial for maintaining the longevity and health of your hair perm. Here are some general tips to keep your curls looking their best:

  • Use Gentle Hair Products: Opt for shampoos and conditioners specifically formulated for permed hair. These products are gentle and hydrating, helping to maintain your curls’ shape and moisture.
  • Avoid Heat Styling: Minimize heat styling tools, such as flat irons and curling wands, which can damage your curls and cause frizz. If you must use heat, apply a heat protectant spray beforehand.
  • Moisturize Regularly: Use a leave-in conditioner or hair oil to keep your curls hydrated and frizz-free. Regular deep conditioning treatments can also help maintain your hair’s moisture balance.
  • Gently Detangle: Use a wide-toothed comb or your fingers to detangle your hair, starting from the ends and working your way up to the roots. Avoid brushing your curls, as this can cause breakage and frizz.
  • Schedule Regular Trims: Regular trims help keep your hair healthy and prevent split ends. This is especially important for permed hair, as damaged ends can make curls look frizzy and unkempt.
