For those with fine, limp hair, combing it every morning feels like a long battle—your hair, freshly blow-dried and styled, flattens to the ground the moment you bend over. Don’t despair; there’s a solution. The key is using a curling iron with sea salt spray to create a long-lasting, high crown, keeping your hair voluminous and stylish from morning till night.

Many people’s first reaction might be, “Oh dear, my short hair is so fine and soft, it won’t hold up for long even if I curl it!” But that’s not the case. As long as you master the methods, fine and soft hair can easily achieve voluminous curls and a high crown effect. Today, we’ll teach you a comprehensive guide on how to use a curling iron to make fine and soft hair truly “stand up,” from basic principles, preparation steps, and operating techniques to styling and maintenance.


Why is fine, soft hair prone to falling flat? First, understand the nature of your hair type.

Let’s first talk about why your hair always tends to “lie flat on the ground”:

  • The hair is soft,
    fine and light, not stiff enough, and easily sticks to the scalp when slightly damp or oily.
  • If the hair is too smooth, it will soften quickly even when curled, lacking texture support.
  • Fine, soft hair needs extra “gripping” to hold its curls and volume in place if styling products are used improperly or in insufficient quantity.

Many people struggle with curling their hair, and the curls don’t last more than a few hours, mainly due to a lack of support and texture. That’s where a curling iron and sea salt spray come in handy—the former gives the hair shape and support, while the latter adds texture and grip. The combination easily lifts the roots, making the curls last longer.

Step 1: Hair Preparation—Cleansing and Primer

Using a curling iron, the condition of your hair is crucial. Don’t underestimate this step; it directly determines the final curling effect.

1. Clean your hair

Fine, soft hair tends to accumulate oil easily, making it lie flatter against the scalp. Therefore, when washing your hair, be sure to thoroughly clean the roots. Apply conditioner only to the ends to avoid oily roots.

Tip: After washing your hair, gently pat it dry with a towel. Do not rub it vigorously, as this will reduce frizz caused by friction.

2. Spray sea salt spray when the surface is semi-dry.

Spraying sea salt mist on hair when it’s half-dry or slightly damp is most effective. The mist can create a “gripping” effect during the drying process, giving the hair more texture.

Operating steps:

  • Spray evenly from a distance of 15–20 cm from the hair.
  • Gently run your fingers through your hair
  • Wait 30–60 seconds before blow-drying.

Tip: The roots of the hair are more important than the ends, as they directly determine the effect of lifting the crown of the head.

3. Curling Iron partitioning as a base

Divide your hair into two sections, securing the top section with clips and starting with the bottom section. Sectioning your hair in this way ensures even curls and prevents you from messing up the bottom section when curling the top section.

Many people like to curl their hair all at once, but it’s best to do it in sections for short or fine hair; otherwise, the curls will easily flatten.


Step 2: Curling iron hair curling technique

This is the key part; mastering the techniques will make your curls look natural and last longer.

1. Selection of curling iron diameter

For fine, soft hair, it is recommended to use a small curling iron of 20–28 mm, which can create natural curls while maintaining support.

  • Too big: Can’t roll it up
  • Too small: If rolled too tightly, it can make you look older.

2. Segmented curls

Take a 1–2 cm segment at a time and roll it up from the bottom, making sure each segment is rolled in place.

3. Curls in alternating directions

Don’t curl your hair in the same direction; alternating the direction of the curling iron will make the overall curls look more natural and create more layers.

4. Heat and time control

Fine, soft hair cannot withstand high temperatures, so hold each section for 8–12 seconds. Medium to low temperatures are sufficient to allow the curls to take shape.

If left too long, it can easily become frizzy or break, and the curl will look unnatural.

5. Cooling and shaping

After each section is rolled, let the curls cool naturally for 30–60 seconds before releasing them.

  • Cooling is an important step in lock forming.
  • You can use clips to help hold the curl in place and let it cool before releasing it.

Step 3: Spray with sea salt spray to enhance stamina.

a curling iron, lightly spray a layer of sea salt spray and gently massage it with your fingers from top to bottom to make the hair texture and curls more secure.

Tip: After spraying, grab the roots of your hair with your fingers and gently massage them to make your hair more voluminous.


Step 4: Additional tips for enhancing a high crown

  • Before using a curling iron, lightly comb the roots with your fingers to make the hair strands point upwards, making it easier to create volume after curling.
  • After spraying sea salt spray on the hair before curling, you can use a hairdryer on a low heat and blow upwards for 30–60 seconds to slightly open the hair cuticles and make the curl texture last longer.

    Your hair the next day will make it look more natural, with a better balance of curl and volume.

Step 5: Long-term maintenance and daily care

  • Lightly spray with hairspray to maintain curl.
  • Dry cleaning spray: Absorbs oil while increasing grip
  • Avoid touching the roots of your hair frequently to prevent the curls from collapsing.

Tip: When styling your hair each day, you can simply use your hands to gently brush the roots without using a comb to avoid damaging the curls.


Explanation of the principle of sea salt spray

  • Texture: Makes the curl lines more distinct
  • Grip strength: Prevents hair from slipping.
  • Airy feel: Simulates the effect of natural air drying

Be careful not to spray too thickly; otherwise, your hair will easily become dry. You can use a light moisturizing spray or hair oil on the ends.
