INsight Rebuild Treatment

From £22
From 30 mins

The INsight Rebuild Treatment is a professional two-step hair reconstruction service designed for dry, brittle or chemically damaged hair. Using INsight's Hair Filler Serum and Hair Cuticle Sealer, it works to restore strength, shine and manageability, making it a useful option for anyone whose hair has been weakened by colouring, bleaching, heat styling or general wear and tear.

More information

What the treatment involves

At Timba, the process follows a straightforward, salon-only system:

  • Hair is cleansed and towel-dried to prepare it for treatment.
  • Step 1: Hair Filler Serum is applied to gently open the cuticle and deliver reconstructive ingredients into the hair, left on for around 8 to 12 minutes, then rinsed with water only.
  • Step 2: Hair Cuticle Sealer is applied to towel-dried hair to close the cuticle and lock in the treatment, again processed for 8 to 12 minutes before a final water-only rinse.
  • Hair is then dried and styled to finish.

The core treatment takes roughly 16 to 24 minutes, which is why it's typically scheduled as a 20 to 30 minute session, either on its own or alongside a cut, colour or styling appointment.

Who this suits

Rebuild is aimed at hair that needs genuine reconstruction rather than a light refresh:

  • Very dry, brittle or porous hair, including hair weakened by bleaching, colouring, straightening or perming.
  • Hair under repeated heat or mechanical stress from styling.
  • Clients wanting a preventive boost to reinforce healthier hair, though a stylist may suggest gentler care if damage is minimal.

Because it's a professional-only system, our team assesses hair condition first to judge whether Rebuild, or a different approach, is the right fit. Stylists such as Emma Stokes, Hannah James and Katie Williams can advise during a consultation.

Results and repeat treatments

Improvements are often noticeable after a single session, particularly on mildly damaged hair. For hair that's very damaged or sensitised, brand guidance suggests a course of 3 to 5 weekly treatments delivers more lasting reconstruction.

  • Hair typically feels stronger, smoother and shinier.
  • Elasticity improves and brittleness is reduced.
  • Detangling and styling become easier, with less frizz.
  • The treatment does not change hair colour, so it can be paired safely around colour or bleach services depending on hair condition.

Aftercare

No special at-home regimen is required between visits. To help maintain results, it's worth:

  • Using nourishing, gentle haircare suited to damaged hair between salon visits.
  • Limiting excessive heat styling and using heat protection where possible.
  • Mentioning any allergies or scalp sensitivities beforehand, since ingredients, while largely natural in origin, can still carry allergy risk for some clients.
