The Best Salon Hair Straightening Treatments to Try Now

Discover the best smoothing treatments for every hair type

It’s no surprise that sleek, straight hair remains one of the most sought-after looks. From boardroom polish to off-duty chic, straight hair is timeless, versatile, and effortlessly sophisticated. But between humidity, frizz, and the daily hustle, maintaining smooth strands can feel like a full-time job.

Luckily, today’s professional straightening treatments have evolved far beyond the flat iron. They’re safer, more effective, and longer lasting than ever before. At our luxury salons, we specialize in advanced smoothing and straightening treatments, each designed to transform your hair based on your unique texture, goals, and lifestyle.

Below, we break down the best salon hair straightening treatments, so you can find the one that suits your style and lifestyle best.

Magic Sleek

Magic Sleek has become a modern favorite for its natural ingredients and formaldehyde-free formula. This treatment restructures the hair cuticle using nourishing oils and amino acids to smooth and strengthen strands without harsh chemicals.

• What to Expect: The process includes a clarifying cleanse, application, heat sealing with a flat iron, and final styling. The result is sleek, shiny hair with a soft, natural feel – and no waiting period to wash or style afterward.
• Best For: Those who want a long-lasting, ultra-smooth finish without damage or downtime.
• Results Last: Up to 4–6 months with proper care.
• Why It’s Loved: Delivers a glassy, polished look while maintaining the health and flexibility of your hair.

Hair B

Hair B is a next-generation smoothing system that bridges the gap between keratin and amino acid–based technologies. Designed for all hair types, it restores moisture, seals the cuticle, and enhances shine – without compromising texture.

• What to Expect: Hair B works by infusing the hair with a rich blend of proteins and hydrating agents, leaving it silky, manageable, and resilient. The treatment can be tailored for a straighter finish or a more natural, flowing smoothness.
• Best For: Anyone with frizz-prone, dry, or damaged hair looking to improve texture and shine.
• Results Last: Around 4–6 months.
• Why It’s Loved: Offers customizable smoothness and long-term strengthening with a soft, touchable finish.

Lasio Keratin Treatment

Lasio is a lightweight, water-based keratin treatment known for its quick processing time and flexible results. It smooths the hair cuticle while maintaining volume and movement, perfect for clients who don’t want their hair to feel weighed down.

• What to Expect: After a deep cleanse, the Lasio formula is applied and heat-sealed. You can wash your hair as soon as 24 hours later – much sooner than with many traditional keratin systems.
• Best For: Fine to medium textures seeking smoother, frizz-free hair without losing natural body.
• Results Last: 3–4 months.
• Why It’s Loved: Fast, effective, and gentle. It’s ideal for those seeking smooth, soft, and manageable hair with minimal downtime.

Keratin Treatment

The classic Keratin Treatment remains one of the most trusted smoothing services. Using keratin – the protein that naturally strengthens hair – this treatment fills in porous strands to reduce frizz, add shine, and improve manageability.

• What to Expect: After cleansing, the keratin formula is applied, blow-dried, and flat-ironed to lock in the treatment. The result is smoother, shinier hair that’s easier to style.
• Best For: Medium to thick hair that tends to frizz or react to humidity.
• Results Last: 3–5 months, depending on hair care routine.
• Why It’s Loved: Enhances shine and smoothness while retaining a bit of natural movement and wave.

Brazilian Blowout

Known for its signature glossy finish, the Brazilian Blowout forms a protective layer around each strand to eliminate frizz and smooth the cuticle. Unlike permanent straighteners, it enhances rather than alters your natural texture.

• What to Expect: A keratin-infused serum is applied, blow-dried, and sealed with heat. The process leaves hair frizz-free, shiny, and more resilient – without removing body or bounce.
• Best For: Those who want smoother, more manageable hair without going pin-straight.
• Results Last: About 10–12 weeks.
• Why It’s Loved: Quick, flexible, and perfect for maintaining natural movement while fighting frizz.

Japanese Hair Straightening (Thermal Reconditioning)

For clients who want permanent straightness, Japanese Hair Straightening offers a dramatic transformation. This method restructures the hair bonds to deliver a sleek, glass-like finish that lasts until new growth appears.

• What to Expect: The process includes a chemical softening solution, meticulous flat ironing, and a neutralizer to “lock in” the straight structure. It’s more time-intensive but results in a lasting, low-maintenance look.
• Best For: Curly, coarse, or highly textured hair seeking a permanent straight effect.
• Results Last: Permanent on treated hair; only new growth requires touch-ups every 4–6 months.
• Why It’s Loved: Delivers a flawless, straight finish that stays sleek even in humidity.

How to Maintain Your Results

To extend the life of your straightening treatment, salon care shouldn’t end when you leave the chair. Follow these simple steps to keep your hair smooth, shiny, and healthy:

• Use Sulfate-Free Shampoo and Conditioner: Harsh detergents strip away the smoothing ingredients and natural oils that protect your hair.
• Avoid Excessive Heat Styling: While your hair will be easier to manage, limit flat iron and curling iron use to prevent unnecessary damage.
• Deep Condition Weekly: Hydration is key. Use a rich, keratin-safe mask once a week to restore moisture and elasticity.
• Protect from Chlorine and Saltwater: Always rinse your hair before and after swimming, or wear a protective cap to avoid fading your treatment.
• Schedule Maintenance Appointments: Depending on your treatment, touch-ups every 3–6 months keep your look consistent and healthy.
