If shiny, strong and bouncy hair is a distant memory, a collagen hair treatment could be the reset your locks need.

Collagen is not just skin’s favourite ingredient; it’s also great for hair care. You will find it in shampoos, conditioners, and treatments, all promising to tame frizz and enhance shine.
If you want to know whether a collagen hair treatment is just another trend or actually delivers, this post tells you everything you need to know.
Let’s break it all down: the cost, whether it’s actually good for your hair, how long it lasts, and how it compares to a keratin treatment.
What Is A Collagen Hair Treatment?
A collagen hair treatment is a deep conditioning product, usually in the form of collagen peptides or hydrolysed collagen. It is applied directly onto the hair shaft and scalp to improve shine, texture and volume.
Collagen hair treatments are usually built around hydrolysed or marine collagen as the star ingredient, paired with a handful of supporting actives:
- Hydrolysed or marine collagen – the key ingredient
- Cetrimonium chloride, cetearyl alcohol, stearyl alcohol – conditioning agents for softness and shine
- Hyaluronic acid, propylene glycol, Butylene glycol – hydrators that lock in moisture
- Argan oil, coconut oil, shea butter (Butyrospermum parkii) – nourishing oils and fatty acids
- Citric acid – balances pH
- Benzyl alcohol – preservative
- Vitamin B and amino acids – support the hair’s own building blocks
Is Collagen Treatment Good For Your Hair?
Yes! For most hair types, a collagen hair treatment is an excellent option, especially if your hair is dry, damaged, brittle or prone to split ends.
Chemical treatments, heat styling and pollution cause natural collagen levels in the hair and skin to decline. This leaves our hair more prone to dryness, brittleness and breakage. This is where collagen products can help restore our locks to their former glory.
Benefits Of A Collagen Hair Treatment:
- Improves hair texture
- Boosts shine
- Adds volume
- Strengthens for more manageable hair
- Tames frizz
- Restores and smooths damaged or brittle hair

Different hair types will have different results, so while a collagen hair treatment is a great option for many, it’s not a magic fix for every hair concern. Any hair loss caused by an underlying health issue or genetics should always be checked by a doctor first.
How Long Does A Collagen Hair Treatment Last?
This depends on whether you opt for a professional service at a salon or an at-home collagen hair treatment.
A professional hair collagen treatment: this is more intensive, and results typically last up to 6 weeks, depending on your hair type and proper aftercare.
An at-home collagen hair treatment: the results are visible almost immediately but will fade after a few washes. They are a cheaper option to use regularly if you want instantaneous results.
How Much Is a Collagen Hair Treatment?
At-home collagen hair masks and shampoos start from as little as £5 on the high street, while an in-salon collagen hair treatment can run anywhere from £70 to £200+, depending on hair length, thickness and how long the treatment is.
Collagen Or Keratin: Which Is Better For Hair?

This is a common hair care question, and the answer depends on what your hair actually needs.
Keratin makes up around 90% of the hair shaft and is the primary structural protein responsible for hair strength and protection. Collagen, on the other hand, builds the foundation and supplies the raw materials.
In practical terms:
- Choose a keratin treatment if: your hair is frizzy, curly, chemically processed, or you want a smoother hair texture and reduced hair frizz that lasts several months.
- Choose a collagen hair treatment if: your hair is fine, thin or lacking in elasticity and volume, and you want a lighter, more manageable finish without weighing it down.
The Takeaway
So, is a collagen hair treatment good for your hair? For most hair types, especially dry, damaged or fine hair, it is a beneficial treatment that boosts shine, manageability and overall hair health, particularly when it’s part of a wider hair care routine rather than a one-off fix.
As with any new hair or chemical treatment, if you have any underlying scalp conditions, allergies or signs of hair loss, always check in with a dermatologist or trichologist before diving in.
Whether you opt for a collagen hair mask or a professional hair collagen treatment, being realistic about how long the results will last will help you get the maximum benefits without the disappointment.
Using collagen to treat your hair will unlock stronger, shinier, and more manageable hair that feels as healthy as it looks.
