The Science of Stronger-Looking Hair
CARE BEYOND THE SALON / MUK TREAT PLUS+ BOND RESTORE
Beautiful hair starts beneath the surface. From the protective cuticle to the bonds that contribute to the strength and shape of each strand, understanding your hair helps you choose care with purpose.
01 Understanding the structure of your hair
Hair is made primarily of keratin proteins. Although a single strand looks simple, its layers work together to influence how it feels, reflects light, holds colour and responds to styling.
The cuticle: your hair's outer protection
The cuticle is formed by overlapping cells on the outside of the hair shaft. A smoother, more intact cuticle helps hair feel silky and reflect light. Repeated friction, aggressive heat and chemical processes can wear this surface and increase tangling and roughness.
The cortex: where strength and colour live
Beneath the cuticle sits the cortex. It contains organised keratin structures and natural pigment, and contributes greatly to hair's strength, elasticity and shape. Colouring, lightening and certain chemical services act on this part of the fibre.
The medulla: the central region
Some hair fibres have a central medulla, though it may be interrupted or absent, particularly in finer hair. The cortex and cuticle are the more important regions for everyday conditioning and bond-focused care.
02 What are hair bonds?
Within keratin, different chemical interactions help stabilise the arrangement of proteins. The most familiar types are hydrogen bonds, ionic interactions and disulphide bonds.
Hydrogen bonds
Hydrogen bonds are comparatively weak, temporary interactions that respond to moisture and drying. They help explain why damp hair can be reshaped with a blow-dry or rollers.
Ionic bonds
Also called salt links, ionic interactions depend on electrical charges within the protein. They are sensitive to changes in pH, so chemical treatments and environmental conditions can affect them.
Disulphide bonds
Disulphide bonds are strong covalent links between sulphur-containing amino-acid residues. They help give hair lasting structural stability and are deliberately altered in some permanent reshaping processes.
A useful distinction: a cosmetic bond-care product can help improve the strength, feel and manageability of treated hair, but it cannot make a damaged fibre biologically regenerate or permanently restore every broken bond.
03 What can compromise hair?
Bleaching and oxidative colouring can increase porosity and affect the internal structure of hair. Repeated high temperatures and mechanical friction can weaken the cuticle. Swimming, mineral deposits and styling-product build-up can make hair feel dull, rough or heavy. Because the causes differ, a personalised routine should consider colour history, heat habits, water exposure and hair texture.
04 The technology behind Muk Bond Restore
Muk Treat Plus+ Bond Restore features the QuatProRiceA Peptide Complex, also known as QPC. Muk describes the system as helping support molecular interactions in hair while improving the look and feel of compromised strands. The complex brings together several conditioning ingredients.
Hydrolysed rice protein
Smaller plant-derived protein fragments used in haircare to support a fuller, more conditioned feel.
Sodium PCA
A moisture-binding ingredient that contributes to hydration and softness.
Arginine and proline
Amino acids used within the formulation as part of Muk's approach to hair conditioning and care.
Statements about bond stabilisation and measured performance are the manufacturer's formulation and test claims. They should not be mistaken for a guarantee of identical results on every hair type.
05 In the salon: Detox. Restore. Regenerate.
The professional Bond Restore system is a salon-led treatment process. It is distinct from the retail products you use between appointments.
Step 1: Bond Detoxing Mist
A professional preparation product used before an appropriate chemical service. This is not the same product as Bond Detox Shampoo, which is a retail cleanser.
Step 2: Bond Restoring Mask
A rinse-off conditioning treatment used to support the feel, strength and manageability of compromised hair.
Step 3: Bond Regenerating Cream
A leave-in conditioning finishing step designed to support softness, shine and styling.
Your colourist selects the professional process according to your hair history and the service being carried out.
06 Care beyond the salon: choosing your homecare
Not everyone needs all five products. A targeted routine is often more useful than buying every treatment without considering your hair's needs.
Bond Detox Shampoo
A cleansing option when product build-up, mineral deposits and swimming exposure are concerns. Consider this when your hair needs a detoxifying wash rather than only regular cleansing.
Bond Post Colour Shampoo
A care-focused cleansing option developed for coloured or stressed hair, designed to fit into a maintenance routine.
Bond Post Colour Conditioner
The everyday conditioning step to help soften, detangle and improve manageability after washing.
Bond Restoring Mask
A richer rinse-off treatment for hair that would benefit from extra conditioning.
Bond Regenerating Cream
A leave-in option for lengths and ends to support softness, shine and manageability before styling.
Professional knowledge. Personal care.
The right routine begins with your hair, not a shopping list. At Studio Junction Hair, we believe in explaining the science simply, selecting products thoughtfully and helping you maintain your hair between appointments.
A note on the science
These explanations are educational and simplified. Product performance claims originate from Muk unless otherwise stated. Visible results depend on hair condition, treatment history and use. Professional chemical-service steps should not be attempted at home.
