FAQs 

1 - What is this treatment and who should use it?

• It’s a protein-reconstructing rinse-out treatment formulated for highly damaged, brittle, chemically treated, or over-processed hair. 

• Recommended for clients whose hair needs more strength, elasticity, and resilience — especially if they bleach, colour, heat-style, or chemically process their hair often. 

2 - What benefits does it provide?

• Reconstructs damaged hair proteins and strengthens strands from root to tip. 

• Helps prevent breakage and split ends, making hair more resilient to future chemical or styling damage. Adds strength and manageability without weighing hair down — ideal when hair feels fragile or limp after treatments. 

• Prepares hair for chemical services (colour, bleaching, perms) by rebuilding strength and helping even out porosity. 

3 - How should it be used (salon or at-home)?

1. After shampooing (preferably with a strengthening shampoo), spray the treatment evenly on wet hair. 

2. Lather and let it sit for 3–5 minutes.

3. Rinse thoroughly. For best results, use 1–3 times per week depending on hair condition. 

4. Optionally, follow with a conditioner or mask for additional moisture or after heavy processing/treatments. 

4 - Will it weigh hair down or interfere with styling?

• No — the formula is designed to strengthen and reconstruct without heavy buildup or weight, so hair remains soft, light, and styling-ready. 

• Because it adds protein and strengthens from within, hair is less likely to break during styling, even with heat or chemical treatments. 

5 - Why choose this treatment instead of a regular conditioner or mask?

• It targets internal protein reconstruction rather than just surface conditioning — useful for hair that’s been structurally compromised from bleaching, colouring or heat.

• It gives quick, noticeable strengthening and helps maintain hair integrity — a valuable maintenance or repair treatment, not just a cosmetic conditioning step. 

• For stylists and salons: great as a prep before colour or chemical services and as a “rescue” treatment for clients with damaged locks — helping make retail and treatment upsells more credible.
