Haircare FAQs

Here you will find the answers to all things Absolute Collagen haircare. If you can't find what you're looking for, please get in touch.

Is the thickening shampoo and conditioner suitable for all hair types?

Yes. However our formulae is developed for use on fine and thin hair. Other hair types are likely to still see benefits like an improvement to hair health, hair manageability, and frizz control.

Can I use it on coloured or bleached hair?


How much should I use?

You only need to use a small amount of the shampoo and conditioner as they are powerful and effective - we recommend using an amount that’s roughly the size of a 10p coin.

Should I use a clarifying shampoo?

No. Clarifying shampoo strips the hair right back, and as Absolute Collagen’s shampoo and conditioner contains natural, mild products that are water soluble they will build up but not to the point where they are excessive, so using a clarifying shampoo would remove this built up product and you would need to start again.

My hair gets used to shampoos and conditioners, will I need to change them?

No. As you age, your hair needs regular use of a shampoo to maintain its condition. If you change, the benefits you've accumulated from regular use will disappear - plus, these products have been developed to work consistently over long periods of time.

I straighten, curl or heat treat my hair - can I use these products?

Yes, you can use our products alongside your heat treatments.

How are these products better than bond builders?

Bond builders are for chemically damaged hair. Due to their formulation, they can deposit and weigh down thin or fine hair. We’ve formulated our shampoo and conditioner to boost thickness and volume while leaving hair light and weightless

What makes these products better than others?

These products have been expertly formulated for thin, fine hair. The shampoo delivers very mild cleansing with active ingredients, cleansing the hair and scalp and depositing the collagen complex onto the hair. In the conditioner, high levels of actives in the collagen complex penetrate the cortex and wrap the cuticle to thicken and strengthen without weighing down the hair where other thickening products build up and leave fine hair feeling heavy and lank.

What if I have hair extensions?

Use the products recommended by your hair extension manufacturer or salon.

What if I have clinical scalp or hair conditions?

If you have clinical problems, you should always see a specialist.

What if I have a sensitive scalp?

Our formulations are mild and can be used on all hair types. However, if you experience irritation, stop using the products immediately and seek advice.

Are these products vegan?

No, as they contain collagen. They are not vegan or vegetarian friendly.

Do these products contain parabens?


Are these products cruelty free?

Our products are not tested on animals.

Do I need these products and the drink or can I cancel the drink?

These products work alongside the drink. Absolute Collagen contains all the essential amino acids your hair needs for a good hair growth cycle, whereas these products contain soluble collagen to wrap your hair and protect it, as well as collagen amino acids which penetrate the hair’s cortex to strengthen it from within. They’ve been expertly developed to work alongside the drink to help your hair inside and out. The drink also delivers powerful benefits for skin and nails, which these products will not affect.

Can I leave the conditioner on as a mask / how long should I leave the conditioner on?

We would recommend you leave you on the conditioner for 3-5 minutes after massaging it in, so the formulation can wrap around the hair and nourish the hair.
Where are your products manufactured?
Our haircare range is manufactured in the UK.

What is the shelf life of your haircare products?

Our products are tested to have a shelf life of more than 30 months and so are not required to have a specified expiry date. We recommend keeping our products away from direct sunlight and any heat sources.

Do your haircare products contain nuts?

Our conditioner contains the following nut:
Cocos Nucifera (Coconut) Oil
Prunus Amygdalus Dulcis (Sweet Almond) Oil

If you have any concerns at all we advise that you consult your GP or pharmacist and show them the ingredient list before using any of our products.

Can I recycle the bottle?

Yes, it is 100% recyclable.

Is the bottle made of recycled plastic?

Yes, we use 50% post consumer recycled plastic, which is plastic made from post consumer waste.

Do you use preservatives?

Yes, we do. We use a small amount of preservatives to protect the products from bacteria growth which is why we are not 100% natural. We are continually reviewing the preservatives that we use and will always keep these at a minimum.

Do these products contain silicones?

Shampoo - no
Conditioner - yes
Yes, the conditioner contains a great silicone called Amodimethicone, which is water-soluble and has good moisturising and cuticle-smoothing effects. It’s also removed with every hair wash due to being water-soluble, so does not build up.

As with sulphates there are a wide range of silicones for hair product use. One such silicone is called Dimethicone, this is the one that can cause problems because it can coat the hair and prevent substances getting in or out. This is why, in the past, 2-in-1 shampoo with high levels of dimethicone could prevent hair colourings and perms from taking properly. Other types of silicones are ones like Cyclopentacyloxane, which are highly volatile which make good vehicles for delivering other material, but leave very little residue on the hair so cause no problems.

Finally, there are great silicones such as Amodimethicone. This is the water-soluble type used in the AC conditioner because it has a nice moisturising and cuticle-smoothing effect on the hair, and because it is water-soluble it is removed every time the hair is washed – unlike water-INSOLUBLE Dimethicone.

Do these products contain sulphates?

Our products contain no SLS & SLES (harsh sulphates) - only an extremely gentle high quality sulphate (TEA-Lauryl Sulphate). The right sulphates are the best way of avoiding problems of scalp imbalance. The most common SLS sulphates can be quite harsh and drying, so we chose a gentle but effective sulphate so that the job of cleaning is done very effectively with no drying to the scalp or hair.

What type of collagen is in these products?

The collagen in our shampoo and conditioner is a mixture of both bovine and marine. This means the products are not suitable for vegans or vegetarians.

Can I get an allergic reaction from using the Absolute Collagen hair range?

All of our ingredients are on the website and back of pack, we would recommend for you to check before purchase. Although allergic reactions are rare, it is possible to be allergic to pretty much anything, including essential oils and other natural ingredients. If you suspect you have a sensitivity, we would strongly recommend that you patch test a small amount of any new product on the inside of your elbow. If you experience any redness or tingling please stop using the product and consult a doctor.

What’s the full list of ingredients?

See ingredients list on the product page

Can I use the shampoo without the conditioner or vice versa?

Yes, you can, however we recommend you use the shampoo and conditioner together as they work in conjunction with each other and have been expertly and specifically formulated to work together.

How frequently should I wash my hair?

We recommend you wash your hair a minimum of 5 times a week for optimum results, as this will help keep your scalp clean and balanced, however we understand this isn’t suitable for all lifestyles. Every other day will also work well, but it may take longer to see results.

Do I need to subscribe or can I just purchase these products as one-offs?

For best results we’d recommend using these products every day on an ongoing basis. Plus, by subscribing you’ll never run out as we’ll deliver to your door every 8 weeks, and you’ll get our shampoo and conditioner for the exclusive subscription price of £28.

If you run out before the 8 weeks, you can bring your next subscription delivery date forwards.
