Hair Extension Guide

Choosing the right hair extension method, length and quantity is essential for achieving a seamless, comfortable and professional result.

This guide is designed to help hairstylists, extension specialists and salon professionals select the best option for each client.

Choose the Right Extension Method

The best method depends on the client’s natural hair, density, lifestyle, desired result and maintenance commitment.

I-Tip Extensions

I-Tips are installed strand by strand using beads or rings, without heat or adhesive.

Recommended for clients who want:

  • A strand-by-strand installation

  • Natural movement

  • Flexible styling

  • Customized volume and length

  • A method without adhesive

I-Tips may be suitable for clients with medium to thick natural hair. Proper sectioning, bead selection and professional installation are essential.

K-Tip Extensions

K-Tips are installed strand by strand using a keratin bond and controlled heat.

Recommended for clients who want:

  • A discreet attachment

  • Natural movement

  • Long-term wear

  • Customized placement

  • Added length and volume

K-Tips require professional installation, removal and regular maintenance. They are not reusable in the same form after removal.

Tape-In Extensions

Tape-Ins are installed using thin adhesive tabs placed between sections of the client’s natural hair.

Recommended for clients who want:

  • A fast installation

  • Flat and discreet attachment points

  • Added volume and length

  • Comfortable everyday wear

  • A reusable extension method

Tape-Ins may be suitable for fine to medium-density hair when installed with the correct placement and weight distribution.

Weft Extensions

Wefts are installed using rows and may be sewn, beaded or applied with another professional weft technique.

Recommended for clients who want:

  • Maximum volume

  • Fuller transformations

  • Fewer attachment points

  • Reusable hair

  • Efficient installation for dense results

Wefts are commonly recommended for clients with medium to thick natural hair. The installer must select the appropriate row placement and amount of hair.

How Much Hair Does My Client Need?

The amount of hair required depends on:

  • Natural hair density

  • Current hair length

  • Desired final length

  • Desired volume

  • Extension method

  • Hair texture

  • Whether the goal is volume, length or both

General Quantity Guide

Volume Only:
Approximately 50–100 grams

Light Length and Volume:
Approximately 100–150 grams

Full Length and Volume:
Approximately 150–200 grams

High-Density or Dramatic Transformation:
Approximately 200–300 grams or more

These quantities are general recommendations. A professional consultation should be completed before ordering.

Clients with short, thick or blunt-cut hair may require additional grams for proper blending.

How to Choose the Right Length

The final length depends on the client’s height, torso length, natural hair and desired result.

General length reference:

  • 16 inches: Around shoulder-blade level

  • 18 inches: Mid-back

  • 20 inches: Lower mid-back

  • 22 inches: Waist area

  • 24 inches: Below the waist

  • 26 inches and longer: Extra-long result

Length may appear different depending on the client’s height, texture and natural hair density.

Curly or wavy hair may appear shorter than straight hair of the same measured length.

Choosing the Right Color

For the most natural blend, match the extensions to the client’s mid-lengths and ends rather than the roots.

When the client has highlights, balayage or multiple tones, combining two or more shades may create a more dimensional result.

For color-match assistance, send clear photos taken in natural daylight without filters, flash or artificial lighting.

Choosing Hair for Volume Only

For clients who are satisfied with their current length but want fuller hair, select a length close to their natural hair.

Using a similar length allows the extensions to blend more easily and creates natural-looking density.

Choosing Hair for Length and Volume

When adding significant length, enough hair must be used to balance the client’s natural density and avoid a thin or uneven result.

Short, thick or blunt natural hair usually requires more grams and careful blending.

Professional Consultation

Before placing an order, evaluate:

  • Natural hair density

  • Hair and scalp condition

  • Previous chemical services

  • Desired result

  • Lifestyle

  • Maintenance commitment

  • Preferred method

  • Required grams

  • Color and undertone

  • Installation suitability

Not every extension method is appropriate for every client.

The professional installer is responsible for determining whether the client is a suitable candidate for the selected technique.

Installation and Maintenance

Hair extensions should be installed, removed and maintained by a trained professional.

Improper placement, excessive tension, incorrect sectioning or unsuitable attachment sizes may affect the client’s natural hair and the performance of the extensions.

Maintenance frequency varies by method, natural hair growth and lifestyle.

The installer should provide a personalized maintenance schedule and complete aftercare instructions.

Aftercare Essentials

For the best results:

  • Use extension-safe products

  • Avoid applying oils or conditioner directly to attachment points

  • Brush gently from the ends upward

  • Support the attachment points while brushing

  • Never sleep with wet hair

  • Use heat protectant before styling

  • Avoid excessive heat

  • Secure the hair in a loose braid or ponytail before sleeping

  • Attend professional maintenance appointments as recommended

Can the Hair Be Colored?

The hair may be professionally toned or darkened after completing a strand test.

Bleaching or lightening is not recommended because it may affect the quality, texture and lifespan of the hair.

Chemically altered hair may not be eligible for return or guarantee review.

How Long Does the Hair Last?

With proper professional installation, regular maintenance and the correct home-care routine, Loviisa Pro Hair extensions may last approximately 7–12 months.

The actual lifespan depends on the extension method, frequency of wear, products used, heat exposure, chemical processing and daily maintenance.

The 7–12-month timeframe is an estimate and not a guaranteed lifespan.
