What Does Olaplex No 4 Do?

Olaplex No. 4 is a Bond Maintenance Shampoo that is designed to strengthen and repair damaged hair. It does more than just protect hair, it helps restore hair bonds and reduce breakage, leading to healthier, smoother, and shinier hair. This shampoo can be used on all types of hair, including curly hair, and is effective for helping repair hair damaged by heat or chemical treatments such as perms or colouring. It is free of sulphates and safe to use on Keratin treated hair. Olaplex No 4 is designed to be colour-safe so it is ideal for use on coloured hair to help retain its vibrancy and prevent fading.

How Often Should Olaplex No 4 be Used?

Olaplex No. 4 can be used with every wash including daily washing. It is suitable for all hair types and textures and for best results can be followed up with Olaplex No 5 Bond Maintenance Conditioner but can be used alone. Olaplex No. 5 is a complementary conditioner that can be used after Olaplex No. 4 to help further moisturise and protect the hair. 

How to Use Olaplex No 4?

Apply Olaplex No 4 to clean, damp hair and massage throughout the hair. Leave on for several minutes and then rinse thoroughly. Only a small amount of product is needed for each wash. You can gently lather some Olaplex No 4. in your hands immediately before applying to help activate the lather so it gets to work extra quickly.

  • Remy hair is human hair that has been cut and maintained with the cuticles aligned and bound together at the top of the bundle, it is the highest grade of hair you can purchase on the market. This process is important to ensure the hair used mimics that of natural hair grown from the scalp because all hair flows naturally from the same direction, this is what allows remy hair extensions to be and feel soft and silky. 


  • The lifespan expectancy of our hair extensions will always depend on how well you maintain them. However, we are confident in saying our extensions can last anywhere from 6 to 12 months.  It is important to know how to care for your hair extensions, such as how often to wash them and how to wash them. Storing your extensions plays a vital part in the lifespan of your extensions too and making sure your set is always gently brushed before, during and after every wear to prolong your extensions lifespan. 


  • Depending on the style of hair extension and the application that follows will determine the risk of damage to your natural hair. Although we use ingredients such as keratin to protect the hair from damage, the removable process can cause slight damage if not done correctly. If you want to avoid damage entirely we recommend using temporary styles such as clip in’s or halos because both types require no heat, glue or bonding like permanent styles do. 

  • Of course! We provide 100% human hair therefore they can be dyed and treated like your natural hair. However, we don't condone lifting the extensions because it’ll damage the extensions worse than you’re natural hair because it’s not receiving the nutrients needed from your scalps natural oils. We recommend using demi or semi permanent hair dye to deposit into the extensions. You should only dye your extensions a darker colour rather than lifting it to be lighter.

  • You sure can! If you purchase any of our extensions they can easily be toned to appear brighter in colour. Depending on the shampoo you use and how pigmented the violet is will differ on what results you’ll get. If you don't have permanent hair extensions, we recommend toning your extensions in a luke warm bath made of diluted purple shampoo and dipping them in the water and quickly rinsing them in a separate bowl of clear water.

  • All of our extensions have been sourced in China. We pride ourselves on providing high quality hair extensions that have be sourced ethically. The hair supplied to Hey Stacey cannot be found anywhere else because it is specifically sourced and supplied to Hey Stacey. We are confident you will not find higher quality anywhere else.
