Nashi Filler Therapy prices can vary depending on the salon, your hair length, and how much product your hair needs. Longer or thicker hair often needs product. That extra product can raise the cost. The treatment is made for hair that feels dry, brittle, weak, or stressed. Because of that, this treatment is not the same as a conditioning service. This guide looks at Nashi Filler Therapy costs in the UK and London, what the treatment price can include, what affects the final cost, and the Nashi treatment system itself. It also looks at Patel Sisters’ Nashi Filler Therapy service and pricing, so you can understand what you are paying for before booking.
What Is Inside Nashi Filler Therapy?
Nashi Filler Therapy uses a combination of conditioning and restructuring ingredients aimed at hair that has lost strength, softness, or elasticity. The treatment does not simply coat hair to make it feel smoother. The treatment is designed to work on the condition of stressed hair.

Collagen, Elastin, and Keratin
Ingredients matter because damaged hair feels rough, weak, and not easy to bend. Ingredients make damaged hair feel smoother, stronger, and easier to move. It doesn’t bend easily. Nashi Filler Therapy has collagen, elastin, and keratin to help make the hair feel better, stronger, and more stretchy. The goal is hair that looks smoother and feels easier to handle after the treatment, not hair that looks good for a little while.
The Role of Phyto Stem Cells
Phyto stem cells are another part of the Nashi Filler Therapy formula. They are included as part of the treatment’s approach to supporting weakened and stressed hair. This makes the formula more than a basic conditioning treatment, particularly for hair that has been affected by coloring, bleaching, heat, or repeated styling.
The Nashi Filler Therapy Product System
The treatment works as a professional product system rather than one single product. Nashi’s system includes products used at different stages of the service, from preparing the hair to applying the filler treatment and completing the final care. This is important when comparing prices because the treatment cost reflects the products used, the amount required, and the professional application, not simply one bottle of product.
Nashi Filler Therapy Cost in the UK
Nashi Filler Therapy prices in the UK can vary depending on the salon, hair length, and how much product your hair needs. Longer or thicker hair may cost more because it can require additional product.
What Are Salons Charging for Nashi Filler Therapy?
Published UK salon prices show that Nashi Filler Therapy can start from around £35–£45, while longer or more product-intensive appointments can cost considerably more. One UK salon specifically confirms that its price can change according to hair length, thickness, and products used.
| Hair Length | Lower-Range Salon Price | Mid-Range Salon Price | Higher-Range Salon Price |
|---|---|---|---|
| Short Hair | £35 | £45 | £52 |
| Medium Hair | £45 | £52 | £61 |
| Long Hair | £50 | £61 | £70 |
| Very Long Hair | £70 | £80 | £95 |
What Could Nashi Filler Therapy Maintenance Cost?
If you plan to continue with the treatment, it is useful to consider the cost of regular maintenance rather than looking only at one appointment. Nashi states that the benefits can be maintained with suitable home products, while one UK salon recommends its Filler Therapy treatment around once a month.
| Maintenance Option | Treatments | Price Guide |
|---|---|---|
| One-Off Filler Therapy | 1 treatment | £35–£95 |
| Regular Maintenance | 1 treatment every 4 weeks | £455–£1,235 per year |
| Three-Treatment Course | 3 treatments | £105–£285 |
| Homecare Maintenance | Shampoo, conditioner & mask | From €71.50 |
How Hair Length and Thickness Affect Nashi Filler Therapy Cost
Hair length and thickness can affect the final Nashi Filler Therapy price because they influence how much product is needed. Shorter, finer hair may need less product, while longer or denser hair can require considerably more for even coverage.

Longer Hair May Require More Product
Longer hair requires product in order to cover the entire length properly. A shorter head of hair may use 50–75 ml, while longer hair can need 100–150 ml or even more. The cost of the treatment may rise because the salon changes its price based on hair length or on how much product is used.
Thicker Hair Can Increase Product Usage
Thickness matters as much as length. Fine hair may need a small amount, but thick hair or hair that is very dense may need 150 ml or more to get even coverage. This means that two clients with the same hair length can still pay different prices for treatment.
What Should You Ask Before Booking?
Before booking, make sure to ask if the salon charges for the Nashi Filler Therapy based on hair length, hair thickness, or how much product is used. It is also an idea to find out if the price you are given includes washing your hair, applying the treatment, and finishing your hair. That way you will know what you are paying for before your appointment.
Nashi Filler Therapy Cost in London
London prices can change based on the kind of service you need, the condition of your hair, and how much product is required. When you look at the price and see what the appointment includes, you can get an understanding of the total cost.
What Does a London Nashi Filler Therapy Appointment Cost?
| What May Be Included | London Treatment Price |
|---|---|
| Nashi Filler Therapy with basic hair preparation | £50–£60 |
| Treatment, preparation, and standard finishing | £60–£75 |
| More comprehensive treatment and professional finish | £75–£90 |
| Longer or thicker hair, higher product usage or a more extensive service | £90+ |
Pro Tip 1: These are indicative London price bands, rather than fixed prices for every salon. A starting price may change once the salon assesses your hair.
What Could Add to Your Final London Hair Bill?
| Possible Additional Cost | Typical Price Guide |
|---|---|
| Blow-Dry / Finishing | £20–£35 |
| Haircut | £25–£50 |
| Additional Product | £10–£25+ |
| Extra Styling | £15–£30 |
| Additional Preparation | £10–£20 |
Not every salon charges these services separately. Some include finishing or preparation as part of the Nashi Filler Therapy price, while others list them as extra add-ons. It’s important to check the quote before booking. That way you can compare the total cost instead of just looking at the starting price that’s advertised.
