Silky, smooth hair is a dream for many individuals, but achieving that coveted glossy texture can sometimes be a challenge, especially if you're dealing with dryness, frizz, or damage. Fortunately, hairdressers have a wide array of products and treatments at their disposal to help transform even the most unruly locks into a sleek, silky masterpiece.

What do hairdressers put in your hair to make it silky?

Hairdressers employ a variety of techniques and products to enhance the silkiness and smoothness of hair. Here are some of the most common treatments and ingredients they use to achieve that desired silky texture:

  1. Smoothing Serums and Oils: Hairdressers often apply smoothing serums or hair oils to tame frizz and add a sleek, silky finish. These products typically contain nourishing ingredients like argan oil, moroccan oil, or silicones that help smooth the hair cuticle and lock in moisture.
  2. Keratin Treatments: Keratin treatments are a popular salon service that can significantly improve hair's smoothness and manageability. These treatments infuse the hair with keratin, a protein that helps strengthen and seal the cuticle, resulting in a silky, frizz-free finish that can last for several months.
  3. Glossing Treatments: Glossing treatments are semi-permanent salon services that coat the hair with a protective gloss or sealant. These treatments not only add incredible shine and smoothness but also help to seal the cuticle, reducing frizz and promoting a silky texture.
  4. Deep Conditioning Masks: Intensive deep conditioning masks can help nourish and hydrate dry, damaged hair, making it more manageable and silky. Hairdressers often use masks containing ingredients like shea butter, coconut oil, or plant-based proteins to deeply condition and smooth the hair.
  5. Leave-In Conditioners: Leave-in conditioners are a staple in many salons, as they help to detangle, smooth, and add silkiness to the hair. These lightweight products often contain ingredients like silicones, oils, and humectants to help tame frizz and enhance manageability.

It's important to note that the specific products and treatments used may vary depending on the individual's hair type, texture, and condition, as well as the desired level of smoothness and silkiness.

Understanding Silky Hair

To better appreciate the techniques and products used by hairdressers to achieve silky hair, it's helpful to understand the science behind a smooth, silky texture:

The Hair Cuticle

The outermost layer of the hair strand is called the cuticle, and its condition plays a significant role in determining the hair's overall smoothness and silkiness. When the cuticle is smooth and flat, it allows light to reflect evenly, creating a sleek, shiny appearance. However, when the cuticle is raised or damaged, it can cause light to scatter unevenly, resulting in a rough, dull, and frizzy texture.

Moisture and Nourishment

Dry, dehydrated hair is more prone to frizz, breakage, and an overall rough texture. By infusing the hair with moisture and nourishing ingredients like oils and butters, hairdressers can help smooth the cuticle and improve the hair's overall silkiness and manageability.

Protein and Strength

Damaged or weakened hair can often appear dull and rough due to a compromised internal structure. Treatments like keratin or protein-based masks can help strengthen the hair from the inside out, improving its elasticity and smoothness.

Why Hairdressers Use Leave-In Conditioners

Leave-in conditioners are a go-to product for hairdressers to achieve silky, smooth hair. These conditioners are designed to be applied after washing and left in the hair, offering several benefits that contribute to that coveted silky texture.

1. Moisture Retention

Leave-in conditioners provide long-lasting hydration, which is key for achieving a smooth, silky appearance. Dry hair can often appear frizzy and dull, but leave-in conditioners help lock in moisture, giving the hair a healthy, glossy finish. They prevent the hair from becoming dehydrated, which is a major factor in maintaining silkiness.

2. Smoothing Frizz and Flyaways

One of the primary reasons hairdressers use leave-in conditioners is their ability to smooth frizz and control flyaways. These products coat the hair, helping to seal the cuticle and prevent it from lifting. By doing so, leave-in conditioners create a sleek, polished look without weighing the hair down. This is particularly beneficial for clients with curly or coarse hair, as it helps to maintain softness and manageability.

3. Detangling and Softness

Leave-in conditioners are effective at detangling hair by softening the strands and reducing friction. This makes combing or brushing easier, reducing the risk of breakage. The resulting smoothness makes the hair feel silkier, and the hair appears shinier and healthier, reflecting light better.

4. Protection from Damage

Hairdressers use leave-in conditioners not only for silkiness but also for protection. These products often contain UV filters or heat protectants that shield the hair from environmental factors like sun exposure, pollution, and styling tools. This added layer of protection ensures that the hair remains smooth and healthy over time.

5. Versatility and Ease of Use

Another reason leave-in conditioners are so popular in salons is their convenience. They’re easy to apply, require no rinsing, and provide immediate results. Hairdressers often choose leave-in conditioners for their ability to style and condition hair in one step, leaving clients with smooth, shiny, and manageable hair without the need for heavy styling products.

Common Ingredients in Silky Hair Products

To achieve silky hair, products often contain key ingredients known for their hydrating and smoothing effects:

  1. Silicones (Dimethicone, Cyclopentasiloxane): Smooth the hair cuticle, add shine, and reduce frizz by creating a protective layer.
  2. Natural Oils (Argan, Coconut, Jojoba): Nourish and hydrate, improving softness, shine, and reducing frizz.
  3. Keratin: Strengthens hair, repairs damage, and enhances smoothness by reinforcing the hair structure.
  4. Panthenol (Pro-Vitamin B5): Moisturizes and improves texture, leaving hair soft and silky.
  5. Glycerin: Attracts moisture to the hair, keeping it hydrated and soft.
  6. Aloe Vera: Soothes the scalp, hydrates hair, and promotes smoothness.
  7. Shea Butter: Deeply moisturizes and softens hair, making it silky and smooth.

Tips for Maintaining Silky Hair

While salon treatments can provide an instant boost of silkiness, maintaining that smooth, sleek texture requires ongoing care and attention. Here are some tips to help keep your hair silky and smooth between salon visits:

  1. Use Sulfate-Free Shampoos: Sulfates are harsh cleansing agents that can strip the hair of its natural oils, leading to dryness and frizz. Opt for sulfate-free shampoos and conditioners to gently cleanse while preserving moisture.
  2. Protect from Heat: Excessive heat styling can cause the cuticle to become raised and damaged, resulting in a rough, dry texture. Use heat-protectant products and minimize the use of hot tools when possible.
  3. Embrace Satin or Silk: Swap out cotton pillowcases for satin or silk alternatives, which can help reduce friction and prevent hair from becoming tangled and frizzy overnight.
  4. Deep Condition Regularly: Incorporate weekly deep conditioning treatments into your routine to help nourish and hydrate your hair, promoting a smoother, silkier texture.
  5. Trim Split Ends: Split ends can travel up the hair shaft, causing strands to appear dry and frayed. Regular trims can help remove damaged ends and maintain a smooth, silky appearance.

By combining professional salon treatments with a gentle, nourishing at-home routine, you can achieve and maintain the silky, smooth hair of your dreams. Remember, consistency and patience are key when it comes to transforming and preserving your hair's texture.
