100% Remy human hair: what does it mean?


The quality of human hair extensions depends on more than simply being labelled "human hair," and it all comes down to the cuticles.

With Remy hair, the cuticles remain aligned in the same root-to-tip direction. This helps the individual hairs move more naturally and reduces friction between strands. For clients, this can mean a smoother feel, natural-looking shine and easier manageability when the extensions are properly cared for.

Why choose Remy hair?
 

  • Real look and feel
    Remy hair matches the texture, shine and behaviour of human hair. Hair feels smooth, soft and silky, and is virtually undetectable when blended
     
  • Tangle-free movement
    With the cuticles facing the same direction, hair moves smoothly without snagging on itself for a fluid, natural looking motion
     
  • Limitless styling
    Because the extensions are 100% human hair, they can be coloured and styled just like natural hair
     
  • Longer lifespan and durability 
    Intact cuticles protect the inner core of the hair shaft, boosting their lifespan and offering better value than cheaper alternatives


The DeepIN Hair Signature Weft extensions go one step further with 100% Virgin Remy hair, meaning the hair has not previously undergone chemical processing.

Which DeepIN Hair extension length is right for your client?

There are many factors to consider when choosing the right length hair extensions. Some of these include:

 

  • Height. Depending on the individual's frame, 24"/60cm hair extensions are may fall around the waist on someone who is 5ft 7", but could fall around the hips on someone who is 5ft 4".
     
  • Goal - whether it's volume, length, or both. If your client's main goal is volume, you may wish to opt for shorter lengths to boost fullness without the heavy weight.
     
  • Texture. Extension lengths are measured straight. If your client is aiming for a wavy or curly style, the extensions may need to be 2-4 inches longer than their target length to account for shrinkage.


Remember, once the hair extensions are fitted, they should be shaped and blended into the client's natural hair for a seamless blend, without unnecessarily removing any density.

Professional hair extension maintenance


Semi-permanent hair extensions require regular professional checks.

DeepIN Hair Tape In 2.0 before and after model

For tape extensions, a typical maintenance window is around 6-8 weeks. As hair naturally grows around 1-1.5cm each month, the tapes are pushed further down the hair which can lead to visible edges and tangling. During the maintenance appointment, the tapes are removed and refitted closer to the scalp.

Weft extensions also require professional maintenance every 6-8 weeks as they need to be adjusted, moved up, or re-installed as hair naturally grows out.

Clip-in extensions should be removed after each use.

Advise clients to book a maintenance appointment sooner if they notice:

  • Tape slipping
  • Twisting attachments
  • Dropping rows
  • Root matting
  • Excessive tangling
  • Pulling or discomfort
  • Visible attachments


Correct maintenance helps protect the natural hair and keeps the extensions looking their best. It is recommended to assess tension, roots, tangles and extension condition during removal and reapplication.

How to maintain hair extensions at home


Professional fitting is only part of achieving a great extension result. Correct aftercare is key in helping to maintain their condition and appearance.

  • Wait 48 hours after tape application. Avoid washing freshly applied tape extensions for the first 48 hours, allowing the adhesive bonds time to settle.
     
  • Wash gently. Gently brush through the hair before washing. Use lukewarm water and cleanse gently using an extension-safe, sulphate-free shampoo, avoiding vigorous rubbing or twisting. Many UNITE shampoos are perfect for extensions including the bestselling 7Seconds range.
     
  • Protect the attachment points. Keep conditioner, masks, oils and heavy styling products away from tape tabs and other attachment areas.
     
  • Brush regularly. Start at the ends and gradually work upwards, supporting the roots or attachment areas as you brush. Avoid pulling through knots or tangles.
     
  • Protect hair overnight. Dry the hair completely before sleeping and secure it loosely in a braid or low ponytail.
     
  • Always remove clip-in extensions before going to bed.
     
  • Use heat carefully. Human hair extensions can be styled, but repeated high-temperature styling can affect their lifespan. Use an appropriate heat protection product and avoid excessive heat.
     
  • Take care with colour. Bleaching or colouring extensions is not recommended. Any colour work should be assessed by a professional and strand tested.
FAQs
How do I choose the most suitable hair extension method?

The hair extension method you choose should be based on the client’s natural hair condition, hair density, lifestyle, desired result and commitment to maintenance. Begin with a thorough consultation and assess the condition, strength and density of the client’s natural hair and scalp. Consider their lifestyle, styling habits, desired result and ability to follow the required maintenance programme. Tape extensions provide efficient application and discreet coverage, weft extensions are particularly suitable for creating fullness, and clip-in extensions offer a temporary option. If the natural hair cannot safely support the proposed installation, the service should be adapted or postponed.

Can different hair extension methods or constructions be used together?

Yes, different hair extension methods can be used together. Combining different methods, attachment sizes or shades can produce a more personalised result. For example, a weft may provide the principal length and fullness, while smaller tape extensions can improve coverage or blending in selected areas. Every attachment must remain appropriate for the density of the natural hair supporting it.

How do I determine the correct amount of extension hair?

To select the right amount of hair extensions, assess the client’s natural hair density, length, haircut and desired result. Adding volume generally requires less hair than creating a substantial increase in length. Short, blunt or particularly dense hair usually requires more extension hair to achieve a seamless blend. Avoid adding more weight than the natural hair can safely support.

How can I choose the right colour hair extensions?

Hair extensions should be colour matched to the client’s mid-lengths and ends rather than relying solely on the root colour. Assess the hair in natural daylight wherever possible and consider its undertone, dimension and colour distribution. Blending two or more shades often produces a more natural result than using one uniform colour.

DeepIN Hair extensions are stocked in many of our Sally and Salon Services stores. Use our Click & Collect option to see if your preferred shade(s) are available in your local store.

How can I make a hair extensions look natural?

To ensure your hair extensions looks natural, they must be successfully blended. Successful blending depends on the method placement, colour, texture, quantity, and the finishing cut. Keep the extension attachments away from visible hairlines and areas exposed by the client’s usual parting or hairstyles. Once the extensions are fitted, shape and blend them into the natural hair without unnecessarily removing their density.

How often do hair extensions need to be maintained, refitted or removed?

The maintenance required for hair extensions depends on the attachment method. Clip-in extensions should be removed before sleep. Tape and sewn-in weft methods commonly require maintenance every 6 to 8 weeks, but some clients may need earlier appointments. Do not rely on a fixed timetable alone. Consider the client’s hair growth, attachment movement, natural shedding, matting and overall condition. Book the next visit before the client leaves, and advise clients to book a maintenance appointment sooner if they notice:

  • Tape slipping
  • Twisting attachments
  • Dropping rows
  • Root matting
  • Excessive tangling
  • Pulling or discomfort
  • Visible attachments
How much natural hair should each hair extension attachment support?

Each section of natural hair must be clean, controlled and proportionate to the weight of the extension being attached. A section that is too fine may create excessive tension; one that is too thick can affect security and comfort. The extension should move naturally without pulling, twisting or trapping surrounding hairs.

How close to the scalp should hair extensions be?

You must leave sufficient space for comfortable movement and natural hair growth when applying hair extensions. Attachments placed too close may feel tight, restrict movement and create unnecessary tension. Those placed too far away may become visible, unstable or prone to tangling. Always check comfort before completing the service.

What is the most important rule during removal?

When removing hair extensions, never pull, force or rush an attachment. Use the correct professional tools and remover for the method, support the natural hair and work through each attachment carefully. After removal, gently separate and brush away naturally shed hairs before washing or refitting. Explain this shedding to the client in advance so that it is not mistaken for sudden hair loss.

At Salon Services, we stock a range of DeepIN Hair extension accessories to help ensure their safe removal including tape extension remover.

When should I refuse or postpone a hair extension service?

Do not fit hair extensions if the client has active hair loss, significant breakage, scalp irritation, open wounds, or hair that cannot safely support the proposed service. Recommend appropriate professional advice where necessary and reassess the client when their hair and scalp are in a suitable condition.

Who may not be suitable for tape extensions?

Tape extensions may not be the best option for clients with excessively oily hair or scalp, frequent exposure to water (such as swimming), or styling habits that place considerable tension on the attachments. Suitability must also be assessed carefully where the natural hair is fragile, actively shedding or unable to support the extension weight.

Why are my tape extensions slipping?

Common causes of tape extensions slipping include:

  • Oil, conditioner or product residue near the roots
  • Insufficient cleansing before application
  • Touching the adhesive
  • Taking an incorrect section size
  • Incomplete pressure across the tape
  • Washing too soon after installation, (you must wait 48 hours before washing hair with tape-in extensions)

Both adhesive surfaces must align fully, with no stray hairs crossing the attachment.

Can you colour hair extensions?

Any colour work on DeepIN hair extensions should only be considered professionally after strand testing.

Can you heat style hair extensions?

DeepIN hair extensions should be treated like your own hair, with care and proper heat protection products. Keep the temperature of heat styling tools low, as high heat and repeated styling reduce lifespan.

Can you wash hair extensions?

Yes, you can wash DeepIN hair extensions. Washing hair with semi-permanent extensions such as tape-in, sew-in or bond, and removable clip-in extensions should be done gently to protect the attachments and keep the hair smooth. Clip-in extensions should be removed and washed separately.

First, detangle the hair using a soft brush, starting at the ends and working up to the roots, using your other hand to firmly hold the hair near the bonds or wefts. Using lukewarm water, cleanse the scalp gently using an extension-safe, sulphate-free shampoo, and avoid twisting or rough scrubbing. Avoid conditioner, masks, oils and heavy styling products on tape tabs or attachment points.

Can I sleep in hair extensions?

Clip-in extensions should be removed before sleep. Tape-in and weft extensions can be slept in. Dry hair fully, brush through, and tie hair in a loose braid or low ponytail.

Can I swim in hair extensions?

Swimming in hair extensions needs extra care, as chlorine and salt can dry the hair and affect bonds.

Can hair extensions be reused?

Yes, tape and weft extensions can be reused if they have been professionally removed, properly cared for and remain in suitable condition. Before every refit, inspect the hair and attachment area for tangling, shedding, damage, adhesive residue or deterioration. Replacement tapes, rings or thread must be used as required. Clip-in extensions can be reused as desired.
