Aftercare

Failure to follow the recommended aftercare guidelines may impact the overall performance and longevity of your hair extensions. Below is information on how you can upkeep, protect, and make your extensions flourish.

1. Brushing

You must use an extension-safe hairbrush designed to gently glide through the hair without placing tension on the bonds.

Never:

  • Pull or drag a brush through the hair, especially when knots are present.
  • Brush extensions when they are wet.

When brushing:

  • Always brush from the ends upwards to the roots
  • Work in small sections
  • Support the hair at the root when brushing

This method helps to:

  • Prevent unnecessary tension on the bonds
  • Reduce breakage and snapping (snippage)
  • Avoid tangling and matting

2. Shampoo & Conditioner

Hair extensions should only be washed when absolutely necessary. We recommend washing every 7–10 days, or longer where possible.

Over-washing can lead to:

  • Dryness
  • Loss of softness
  • Reduced lifespan of the hair

You can maintain your natural hair between washes by:

  • Washing the top section only (avoiding the lengths)
  • Using dry shampoo to refresh the roots

Choosing the right shampoo & conditioner is important, it must be a sulfate-free shampoo and conditioner that is clarifying or detoxing, while also being moisturising, it is important to understand that cleansing and moisture must work together.

A shampoo that is too harsh can strip the hair, while one that is too heavy can cause build-up — both will negatively affect the longevity of your extensions.

Avoid shampoos that leave the hair feeling overly “squeaky clean,” as this often indicates the hair has been stripped of essential moisture.

Shampooing Routine

When washing your hair extensions, your focus should always be on the scalp — not the lengths.

  • Shampoo the scalp only
  • Do not shampoo the hair extensions directly
  • Avoid rubbing or scrubbing the mid-lengths and ends

As you rinse the shampoo out, it will naturally flow through the lengths, which is sufficient to cleanse the extensions without causing unnecessary dryness or friction.

This method helps to:

  • Prevent dryness and over-stripping
  • Maintain softness through the lengths
  • Reduce tangling and matting
  • Protect the overall condition of the hair

Always allow the water and product to run downwards, and avoid piling or twisting the hair during washing.

3. Treatment Mask

Hair extensions do not receive natural oils from the scalp, meaning moisture must be replaced manually to maintain softness, shine, and longevity.

  • Use a deep conditioning mask every 7-10 days (or as needed)
  • Apply to mid-lengths and ends only
  • Avoid the roots area, bonds or tapes
  • Leave on for 5-15 minutes, then rinse thoroughly

Focus on keeping the hair hydrated to prevent:

  • Dryness
  • Tangling
  • Dullness

4. Drying

Hair extensions must always be dried correctly after washing to prevent matting, tangling, and damage.

  • Never leave hair extensions to air dry completely
  • Never sleep with wet or damp hair
  • Always ensure the root area, bonds, or tapes are fully dry after washing

Towel Drying

  • Do not rub the hair with a towel
  • If using a towel, use a microfibre towel only
  • Gently squeeze and pat the hair to remove excess water

Blow Drying

  • Always blow-dry the root area thoroughly
  • Mid-lengths and ends can be blow-dried using a brush or left slightly natural once roots are fully dry

Leaving the root area damp can lead to matting and may affect the longevity of your extensions.

5. Heat Protection

Heat protection is essential for maintaining the quality, colour, and condition of your hair extensions.

Always use an effective heat protectant before:

  • Heat styling (straighteners, curling wands, blow drying)
  • Sun exposure (holidays, warm weather, beach days)
  • Sunbeds or UV exposure

Apply evenly through the mid-lengths and ends before any exposure.

Not all heat protectants provide the level of protection required for hair extensions. Using a high-quality, effective formula is essential to prevent dryness, colour fading, and damage.

6. Leave-In Conditioner

Leave-in conditioner helps maintain moisture, softness, and manageability, supporting the overall condition of your hair extensions.

  • Can be applied to damp hair before drying
  • Can also be used on dry hair between washes
  • Spray lightly through the mid-lengths and ends
  • Avoid the root area, bonds, or tapes
  • Allow the product to absorb into the hair, do not rinse.

Usage guidance (important balance):

  • Can be used daily or as needed
  • Use a light amount to avoid product build-up

7. Hair Oil

Hair extensions do not receive natural oils from the scalp, making daily hydration essential to maintain softness, shine, and smoothness.

  • Use a lightweight, argan-infused oil for best results
  • Apply to the mid-lengths and ends only
  • Avoid the root area, bonds, or tapes
  • Apply a small amount once in the morning and once in the evening
  • Can be used throughout the day if needed, using minimal product

8. Heat Styling

Heat styling should always be carried out using controlled, moderate temperatures to protect the condition and colour of your hair extensions.

  • Avoid using heat tools on the highest temperature settings
  • Always opt for a lower or medium heat setting
  • Hair will still style effectively without excessive heat
  • Use straighteners, curling tools, and blow-dryers carefully
  • Avoid applying direct heat to bonds, tapes, or attachment points

Excessive heat can lead to dryness, colour fading, and reduced lifespan of the hair.

Failure to use controlled heat may also cause unnecessary stress to the hair, increasing the risk of breakage.

9. Daily Brushing

Regular brushing is essential to prevent tangling, matting, and unnecessary stress on the hair.

  • Brush your hair 2-3 times daily as a minimum
  • Always use an extension-safe brush
  • Carry a suitable brush with you when out, especially in; wind, busy environments, long days out
  • Gently brush through the hair throughout the day to keep it smooth and tangle-free

10. Sleeping

Proper night-time care is essential to prevent tangling, matting, and unnecessary stress on the hair.

  • Before bed, ensure the hair is fully brushed through and free from tangles
  • Secure the hair in a loose braid or two loose braids
  • Use silk or satin scrunchies (avoid tight or elasticated bands)
  • Wear a silk or satin bonnet where possible
  • Sleep on a silk or satin pillowcase

11. Lifestyle & External Factors

Environmental factors can significantly affect the condition, colour, and longevity of your hair extensions.

Sun Exposure & UV

  • Prolonged exposure to sunlight can cause dryness, colour fading, and brassiness
  • Always apply a heat protectant before sun exposure
  • Where possible, keep hair protected when in strong sunlight

Sunbeds

  • UV exposure from sunbeds can lead to dryness, fading, and colour change
  • Always apply a heat protectant before use
  • Wear a silk or satin bonnet to protect the hair during use

12. Swimming

Chlorine and salt water can dry out the hair and may also cause unwanted colour changes, particularly in lighter shades.

  • Avoid submerging hair in water where possible

If unavoidable:

  • Apply a leave-in conditioner or regular conditioner before swimming
  • Tie the hair up securely
  • Leave the conditioner in while swimming to create a protective barrier

After swimming:

  • Rinse the hair thoroughly as soon as possible
  • Follow with your usual cleansing and conditioning routine

13. Maintenance

Regular maintenance is essential to keep your hair extensions looking and performing at their best.

  • Attend maintenance appointments every 6-8 weeks
  • Do not leave extensions in beyond the recommended timeframes
  • Professional repositioning and upkeep is required to prevent: matting, tangling, and excess tension on natural hair

Hair extensions are a luxury product and require consistent, correct aftercare to maintain their quality and lifespan.

  • Extensions do not receive natural oils from the scalp and must be maintained manually
  • Improper aftercare can lead to: dryness, tangling and matting, colour fading, and reduced lifespan
