OLAPLEX Nº.4FINE Bond Maintenance Volumizing Shampoo 250ml

OLAPLEX Nº.4FINE Bond Maintenance Volumizing Shampoo 250ml is an ultra-lightweight strengthening and volumizing shampoo created specifically for fine hair that needs body, lift and repair without being weighed down.

It gently removes oil, impurities and everyday buildup while helping repair damage and reinforce weakened bonds. Unlike heavier reparative shampoos that can leave fine hair feeling flat, Nº.4FINE is designed to leave hair weightlessly clean, soft, shiny and visibly fuller.

When used as a system with OLAPLEX Nº.5FINE Bond Maintenance Volumizing Conditioner, OLAPLEX reports 2x more volume instantly and throughout the day, 90% more weightless hydration, and 2x stronger hair with less breakage under its specified clinical testing conditions.

Cleanse → Volumize → Strengthen → Repair → Add Body and Bounce

What Does OLAPLEX Nº.4FINE Shampoo Do?

Nº.4FINE combines gentle cleansing, bond repair and lightweight volume in one shampoo.

It helps to:

• Add volume, body and bounce
• Lift fine hair at the roots
• Strengthen fragile hair
• Repair everyday damage
• Help defend against future breakage
• Remove buildup without stripping the hair
• Improve softness and shine
• Hydrate without leaving fine hair heavy
• Support color-treated and chemically treated hair

OLAPLEX specifically formulates it for straight, wavy, curly and coily hair with fine texture, across all porosity levels.

What Results Can You Expect?

When Nº.4FINE Shampoo is used together with Nº.5FINE Volumizing Conditioner, OLAPLEX reports:

2x more volume – instantly and maintained throughout the day
90% more weightless hydration
2x stronger hair with less breakage

The shampoo is also clinically proven to improve softness and shine.

These results are based on OLAPLEX's specified testing conditions and use of the Nº.4FINE and Nº.5FINE system; individual results can vary.

Who Is It For?

Ideal for:

Fine hair
Flat or volume-lacking hair
Fine hair that becomes oily or weighed down easily
Fragile hair prone to breakage
Fine damaged hair
Fine bleached hair
Fine color-treated hair
Chemically treated fine hair
Hair lacking body and root lift
Fine straight, wavy, curly or coily hair

Is Nº.4FINE Only for Thin Hair?

No. Fine hair and thin hair are not the same thing.

Fine hair describes the diameter of each individual strand, whereas thin hair describes the overall density or number of hairs.

You can therefore have very dense hair but still have fine individual strands. Nº.4FINE is primarily designed around fine hair texture.

Pair Me With

OLAPLEX Nº.5FINE Bond Maintenance Volumizing Conditioner is the ideal pairing.

The Nº.4FINE and Nº.5FINE system is specifically designed to provide fine hair with volume, lightweight hydration and strengthening without heaviness. OLAPLEX's headline clinical results are based on using these two products together.

For additional repair, OLAPLEX recommends incorporating Nº.3PLUS Complete Repair Pre-Shampoo Treatment weekly.

Will OLAPLEX Nº.4FINE Weigh Down Fine Hair?

No. This is one of the main problems Nº.4FINE was specifically formulated to address.

Its ultra-light lather removes buildup while maintaining lightweight hydration, helping fine hair retain body, bounce and root lift rather than leaving it flat.

OLAPLEX specifically states that Nº.4FINE should not progressively weigh fine hair down with continued use.

Does Nº.4FINE Actually Add Volume?

Yes. Volume is one of its primary functions.

OLAPLEX reports that Nº.4FINE doubles hair volume, providing body, bounce and root lift when used as part of the Nº.4FINE and Nº.5FINE system. The brand reports that the volume is immediate and maintained throughout the day under its specified testing conditions.

It is important, however, to understand what this means: Nº.4FINE makes hair look and feel more voluminous. It does not permanently increase the number of hair follicles or medically treat thinning hair.

Is Nº.4FINE Good for Oily Fine Hair?

It can be a particularly useful choice when fine hair becomes flat from oil and everyday buildup, because the shampoo is designed to cleanse without leaving the hair heavily conditioned.

However, Nº.4FINE is not a dedicated treatment for an excessively oily scalp. If the primary concern is a persistent scalp condition rather than fine, flat hair, a scalp-specific shampoo may be more appropriate.

Does Nº.4FINE Remove Product Buildup?

It gently lifts away everyday buildup and impurities without stripping the hair.

However, it should not be confused with OLAPLEX Nº.4C Bond Maintenance Clarifying Shampoo, which is specifically designed for deeper clarifying.

For normal washing and everyday buildup → Nº.4FINE

For periodic deep clarification → Nº.4C

OLAPLEX Nº.4FINE vs Nº.4 Bond Maintenance Shampoo

This is one of the most important questions for customers choosing between the two OLAPLEX shampoos.

Choose Nº.4FINE if:

Your hair is fine
Your roots become flat easily
You want more volume and body
You want lightweight hydration
You need strengthening without heaviness
Rich shampoos tend to make your hair feel flat

Choose Nº.4 Bond Maintenance Shampoo if:

Your hair is medium, thick or coarse
Your priority is richer hydration and nourishment
Your hair needs more smoothing
Frizz is a major concern
Volume isn't your primary objective

OLAPLEX describes Nº.4FINE as the ultra-light option specifically formulated to instantly volumize and strengthen fine hair, while the original Nº.4 focuses more heavily on repair, hydration and smoothing.
