Keratin Treatment

Upon Consultation

Eliminate frizz by up to 95% with this unique treatment in our Wellesley Hair Salon. Using the penetrating power of keratin, a natural fibrous protein found in hair that shields against humidity, this treatment leaves your hair smoother, softer, silkier, and shinier. Plus, it defends against environmental humidity and toxins, without causing your hair damage. The result is manageable hair that reduces daily styling time. It is also safe on color-treated hair.

Benefits of Keratin Hair Straightening Treatment

A keratin hair treatment at Bella Santé in Wellesley smooths frizz-prone hair while preserving natural movement. The result is sleek, glossy hair that feels soft and stays consistently polished.

Frizz is significantly reduced, even in humidity, so hair remains smooth and controlled throughout the day. The treatment enhances shine, giving hair a silky, light-reflective finish.

A keratin straightening treatment also makes styling easier. Hair becomes more manageable, with less time needed for blow-drying and heat styling. It falls into place more effortlessly and holds its shape with less work.

Results last for several months with proper care, making this an effective way to maintain smooth, manageable hair over time.

Overall, this treatment delivers smoother, shinier, and more manageable hair while helping simplify your daily routine.

What to Expect During Your Keratin Appointment at Bella Santé's Hair Salon

A keratin treatment at Bella Santé in Wellesley is a precise, customized service designed to deliver smooth, consistent results with attention to detail at every step.

  1. Consultation & Hair Assessment
    Your appointment begins with a consultation to evaluate your hair and understand your goals. This ensures the treatment is tailored to your texture, condition, and styling preferences.
  2. Deep Cleansing
    Hair is thoroughly cleansed to remove buildup and prepare it for even application of the keratin treatment.
  3. Keratin Application
    The keratin formula is applied methodically throughout the hair to support smoother, more manageable results.
  4. Heat Sealing
    A flat iron is used to seal the treatment into the hair, helping set the smoothing effect and enhance shine.

Hair is left smooth, soft, and easier to manage, with reduced frizz and a more controlled finish.

FAQ

Results typically last two to six months, depending on your hair type, the formula used, and how well you maintain the treatment. Coarser hair tends to hold results longer. Using sulfate-free products and limiting wash frequency helps extend the life of your treatment.

Keratin itself is a protein naturally found in hair, so the treatment is not inherently damaging. That said, the heat used during the flat-ironing step can affect hair that is already fragile or compromised. At Bella Santé, every keratin service begins with a thorough consultation and hair assessment to make sure the treatment is appropriate for your hair's current condition.

Keratin treatment smooths the hair cuticle to reduce frizz, boost shine, and improve manageability. It works by infusing keratin protein into the hair shaft, which helps seal out humidity and leaves hair softer, sleeker, and easier to style.

Keratin treatment pricing varies based on hair length, thickness, and the salon. For specific pricing at Bella Santé's Wellesley location, we recommend reaching out directly or booking a free consultation.

Around the two-to-three month mark, results begin to gradually fade as the treatment washes out over time. Hair returns to its natural texture rather than reverting all at once. Many guests choose to book a follow-up treatment at this point to maintain smoothness and manageability.
