Product Description

DSD de Luxe 3.4.1 Ultra Strong Serum is an advanced anti hair loss serum formulated to help reduce excessive shedding and stimulate natural regrowth. Enriched with placental proteins, biotin, caffeine, and botanical extracts, this powerful treatment nourishes the scalp, revitalises follicles, and supports stronger, denser hair. Suitable for both men and women, it’s recognised by many as one of the best hair growth serums for thinning hair.

Why Choose This Hair Growth Serum?

This intensive hair growth serum combines science-backed actives and natural extracts to target the root causes of hair thinning:

Placental proteins & yeast extract – revitalise and nourish the follicle environment

Caffeine & capsicum extract – boost scalp microcirculation and nutrient delivery
Biotin, B-vitamins & panthenol – strengthen hair fibres and improve density
Botanical extracts (nettle, olive leaf, horse chestnut) – regulate oil, calm irritation, and improve scalp balance

Together, these actives make the Ultra Strong Serum a hair growth treatment that actually works when used consistently.

After 56 days of use, hair loss was reduced by 31.23% and hair diameter increased by 2.61%, with clinically significant improvements (p<0.05).

How To Use

Shake the vial before use. Apply half the contents (approx. 2.5 ml) directly to the scalp, either on dry or towel-dried hair. Gently massage into the scalp until fully absorbed.
Do not rinse. For best results, avoid washing the hair immediately after application to allow active ingredients to work effectively.

Use daily for 2 months as an intensive treatment.
Then continue with 3.4 Dixidox de Luxe Forte Lotion for a further 2 months to maintain results.

Apply after washing with 3.1 Dixidox de Luxe Intense Shampoo or as advised by a specialist.

Each vial provides two applications.

Unfortunately, 3.4.1 turned out to be a total disappointment for me - after 2 days of use my head started itching, and this continues days after I stopped using it :( I use a lot of dsd products, and this is the first time I have such reaction

I’ve been using these products for over a year and absolutely love them!

Good

I love it my hair finally started grow

After using these ampoules I had a lot of new baby hairs! Very good quality and high effectiveness! This product works and after using it for a while I noticed my hair started to regrow! I am 100% happy with the results and will recommend it to everyone who suffers hair loss.
Very strong formula which helps to reduce and prevent hair loss.

FAQs

Are these products safe for coloured, bleached, or chemically treated hair?

Yes. All DSD de Luxe products are formulated to be compatible with coloured, bleached, or chemically treated hair - including keratin, relaxers, and highlights.

Can I mix and match products from different DSD Lines?

Yes - DSD systems are designed to work together. You can combine shampoos, lotions, and masks from different phases based on your hair and scalp needs. If you're unsure, we recommend taking our free hair care quiz for a personalised recommendation.

How often should I use these products?

Usage varies depending on the product. Most shampoos can be used 3–4 times per week, while lotions and ampoules may be used daily or as a course. Full usage instructions are always listed under the “How to Use” tab.

Do these products stop hair loss?

DSD products are formulated by trichologists to support scalp health, improve hair density, and reduce excessive shedding. Results vary based on severity, consistency, and product combinations. For best results, we recommend a full system approach.

Are these products suitable for men and women?

Yes - all DSD formulas are unisex and clinically developed to treat the underlying causes of hair loss and scalp imbalance in both men and women.

How long until I see results?

Many users report visible improvements within 4–6 weeks. However, results depend on consistency and severity. For chronic hair loss or scalp issues, a minimum 3-month course is recommended.
