I'm Franny Flynn, owner and sole practitioner at Brazilian Blowout Boston in Quincy. I have been specializing in smoothing treatments since 2009 and have performed over 10,000 treatments in that time. I also wear these treatments on my own hair.

Most clients book initially because of frizz. What they discover afterward is that their color holds longer and their hair breaks less. Let me walk you through why that happens and how I calibrate the treatment for different color situations.

What Color Processing Does to the Hair's Structure

When hair is lightened or colored, the process requires opening the cuticle layer to allow the formula to reach the interior of the hair shaft where pigment change occurs. The degree to which the cuticle is raised depends on how significant the chemical process is. A gentle single-process color raises the cuticle moderately. Repeated lightening raises it significantly and over time increases the hair's porosity throughout the previously processed sections.

Highly porous hair has a cuticle that does not seal tightly after processing. It absorbs moisture from the surrounding air rapidly, which is what causes the expansion and frizz in our coastal Quincy humidity. It also releases the color molecules it just absorbed during the color service more quickly with each subsequent wash because the open cuticle cannot hold them in.

The smoothing treatment's amino acid formula bonds to the cuticle surface under heat and creates a sealed layer. For color-treated hair specifically, that sealed layer is what keeps the color inside rather than releasing it with every wash.

Timing the Smoothing Treatment With Your Color Service

The most effective sequence is to have your color service performed before the smoothing treatment rather than after. Bleaching and lightening specifically should always be done before the treatment, not after, because a sealed cuticle resists the lifting that lightener requires to access the hair's interior.

For single-process color, the treatment can be done before or approximately two weeks after, allowing the cuticle to settle before the smoothing formula is applied. I cover the specific timing for each client's color situation during the free phone consultation before they book. If you are managing your color at another salon, I ask about your color schedule so the two appointments are sequenced correctly rather than inadvertently working against each other.

When the smoothing treatment is applied after a color service, the heat bonding process presses the amino acid formula into the cuticle surface while the color molecules are still fresh. The seal that forms keeps both the treatment and the color in place together, which is why clients who schedule their color before their smoothing appointment consistently notice their color holds longer than it did before they started treatments.

Hyacinth had been getting partial highlights every eight weeks because her toner was washing out within two to three weeks of each appointment. When I spoke with her during her phone consultation, she described the rapid fading and I identified the cuticle porosity from her accumulated lightening history as the most likely cause.

We scheduled her smoothing treatment for the day after her color appointment at her regular salon. At her follow-up appointment ten weeks later her toner was still holding within her acceptable range and she had not needed to return to her colorist between appointments for the first time in over a year.

Blonde Hair: Preventing the Spongy Texture

Heavily highlighted blonde hair is among the hair types I see most frequently where the structural benefit of the treatment is as significant as the frizz reduction. Repeated lightening sessions over months or years produce a hair shaft that is noticeably more porous and fragile than unprocessed hair. The texture clients describe as spongy when wet, or that breaks too easily when brushed, is the result of this accumulated porosity.

The amino acid formula fills the gaps in a compromised cuticle and creates the smooth, solid surface the hair had before the repeated lightening removed it. The hair no longer feels spongy because the porosity that was causing that texture has been addressed at the surface level. The toner applied at the color appointment holds longer because the sealed cuticle retains it rather than releasing it.

For blonde clients whose hair has reached a degree of porosity where even conditioner does not seem to help, I apply the treatment at a lower heat setting for the first session. Compromised hair is more sensitive to the heat required to bond the formula and a gentler first application produces a more subtle initial result that improves across subsequent treatments as the hair's overall condition recovers progressively.

Red Hair: Managing the Fastest-Fading Color

Red hair dye produces the fastest-fading color of any professional hair color because the red pigment molecules are larger than the molecules of other color families and do not embed as deeply into the hair cortex. For clients whose color history includes red or auburn tones, this fading cycle is one of the most consistent frustrations they bring to the consultation.

The sealed cuticle from a smoothing treatment creates a barrier that slows the rate at which the red pigment escapes with each wash. The treatment does not stop the fading entirely, but it meaningfully extends the window between color appointments before the fade becomes noticeable.

Sun exposure accelerates red color fading specifically because UV light degrades the larger red pigment molecules faster than other color families. For clients spending time at Marina Bay or Wollaston Beach through the summer, the sealed surface of a treated cuticle provides a UV barrier that slows this photo-oxidation.

Florencia had vibrant auburn highlights that she was getting refreshed every six weeks specifically because the color was reading significantly faded by week four. During our phone consultation I identified the rapid fading as consistent with the combination of high porosity from her highlight history and summer UV exposure.

We scheduled her treatment for the day after her color appointment. At her follow-up she had extended to nine weeks between color appointments and the color was still holding noticeably better than at any previous cycle.

Gray and Silver Hair: Addressing Texture and Shine

Natural gray and silver hair has a different structural quality than pigmented hair because the melanin that previously filled the hair cortex is no longer present. Without that interior filling, gray hair often feels coarser and more resistant to laying flat than the client's previous pigmented hair. It also reflects light less uniformly because the raised cuticle scatters rather than reflects.

A smoothing treatment smooths the cuticle surface so gray and silver hair reflects light more evenly. The coarseness and resistance that make gray hair difficult to style reduce significantly because the treated cuticle lies flat rather than standing up and resisting direction. Clients who have been fighting a wiry texture since their hair transitioned often describe the treated result as the first time their natural silver has looked intentional rather than unmanageable.

For gray clients who color their silver with a toner or semi-permanent deposit to manage brassiness or add dimension, the same color-sealing benefit applies. The treatment applied after the toning service extends how long the tonal deposit holds before the brassy undertones reassert.

Structural Benefits Beyond Color: Strength and Heat Reduction

The color protection benefit is the one that surprises clients most. The structural benefits are the ones they feel daily.

Because the treated cuticle is sealed rather than open, the hair retains its internal moisture more effectively through New England's dry winter heating and coastal summer conditions. Clients who were fighting brittleness through Quincy winters consistently notice their hair feels better maintained between appointments without any change to their product routine.

The heat reduction benefit is practical and cumulative. Treated hair dries significantly faster than porous hair because it does not absorb as much water during washing. Hair that required forty-five minutes of blow-dry and flat iron work typically requires fifteen to twenty minutes after the treatment because it dries faster and holds its shape after fewer passes of a styling tool.

The reduction in daily heat exposure is meaningful for hair that has already been processed, because each styling session after the treatment causes less additional damage than before it.

When the Treatment Needs Adjustment

I want to be direct about when the standard application is not appropriate. Hair that has been significantly stressed by sun exposure, salt water, or extended heat styling without protective products needs a modified approach rather than the standard protocol. The first session on compromised hair is applied at a lower heat setting that the hair's current condition can support. The initial result is more subtle. Subsequent treatments produce progressively stronger results as the cumulative sealing effect improves the hair's overall condition.

The phone consultation before every new client's first appointment is where I assess whether the standard protocol is appropriate or whether the modified approach makes more sense. I would rather set an accurate expectation in that conversation than have a client arrive expecting a dramatic result that her hair's current condition cannot produce in a single session.
