From fine, flat and lifeless strands to thick, full and enviable hair in an instant, keratin hair fibres are your secret weapon for undetectable coverage. They have a slightly oval cross section with a coating of fine plates on the outside, similar to the hair shaft. This translates into the weight, feel and look of real hair in all light conditions. Unlike long term-term natural keratin treatment options, Nanogen keratin hair fibres deliver instant results that can be washed away at the end of the day.

Keratin in 10 different shades

Available in 10 different shades, Nanogen hair fibres are made from the finest grade keratin coated in a secret process to deliver outstanding results. What exactly is keratin, you might ask? Keratin is a fibrous structural protein found in our nails and skin, and is practically identical to human hair. Keratin works by soothing down the cells that overlap to form your hair strands, adding volume and thickness to your overall doo.

Potential Nanogen hair fibres side effects

As with anything you apply to your body, it is important to question: Are Nanogen hair fibres safe? Is hair fibre harmful? What exactly are hair building fibre side effects? And while the risks associated with hair fibres are incredibly low, we know the importance of having all of the information in one place. Keep reading for a rundown of the most talked about hair fibres side effects. Potential but unlikely side effects of hair building fibre include:

Ammonium Chloride

Some leading brands of hair fibres are formulated with ammonium chloride. This non-organic ingredient can be sourced from a number of things and is often added to fertiliser and to add flavour to liquorice. It can also act as a thickening agent to help dyes stick together. Although ammonium chloride has been declared safe to use topically, any chemical can be hazardous if significant amounts enter the body. Potentially, repeated exposure over time may cause ammonia poisoning, which can cause muscle spasms, irregular breathing, irregular heartbeat, irritation and allergies.

Some hair fibres are made from natural cotton sources to create fibres that look much like hair. However, there are a number of allergies associated with cotton which can cause various hair fibres side effects. Allergies to cotton plant tissues or fibres usually appear as dermatitis, a skin inflammation which can cause rashes and can appear on any part of the body even without direct contact to the allergen. A cotton allergy may also cause respiratory problems including asthma or rhinitis.

Solution: Let’s talk solutions. If you suffer from a cotton allergy, it’s key that you stay away from cotton-based hair fibres to avoid any side effects, and instead opt for other types, like keratin-based fibres.

One hair fibres side effect that is relevant to almost all brands is allergies associated with dyes. Since all hair fibres are dyed to match our hair colour, they do contain colourants - artificial or natural - that could cause allergic reactions such as irritation and redness.

Solution: To see whether you react to the dyes in hair fibres, its best to do a patch test on a small area of skin 24 hours before you start to use them. This will tell you if you have any itchiness, irritation or redness before you continue. Many hair fibres brands sell a trial size within their range, which is a perfect size to try out the product before you invest.

Hair building fibres side effects: Myths debunked

There are a number of myths circulating the internet about the dangers of using hair fibres. We’re here to debunk them so you can be safe in the knowledge that using hair fibres won’t cause the following issues.

Clogged follicles

There’s some scepticism out there that relates to hair fibres clogging follicles and suffocating the hair strand, causing it to fall out. However, this isn’t the case. In fact, hair fibres are the ideal substitute for products like dry shampoos and styling powders which can actually clog follicles and cause hair to fall out. Keratin hair fibres do not clog up the scalp and can be completely removed with an effective cleansing shampoo (for both men and women).

Damaged hair

It’s a myth that hair fibres damage the hair. They do not harm the hair or scalp, particularly those made with 100% natural keratin. Since they are made from the exact same protein as our hair, they do not cause any damage to it, maintaining hair health and strengthening it regardless of fibres.

The impact of hair treatments

Many people think that if they use hair growth treatments such as serums or medication, they cannot use hair fibres too. This simply isn’t true. Why? Because hair fibres do not actually interfere with any hair growth treatments, including minoxidil. Because fibres work by attaching to the hair strand and staying there to build thickness, they don’t actually penetrate into the scalp. This means that they will not block the action of any hair loss treatment serums you’re using. In fact, hair fibres can be a great addition to your hair growth routine by concealing thin areas while you wait for the treatment to ‘kick in’.

Hair fibres side effects vs. Medical solutions

As we’ve mentioned, there are a couple of real hair fibres side effects to consider before using the treatment. And while they can be serious, they are also incredibly unlikely. It’s also essential to compare them to the side effects of other medical hair loss solutions on offer. Any medical procedure or treatment can have a plethora of side effects to think about, particularly if it involves going under the knife or on medication. We’ve looked at some of the most talked about treatments available to see how they stack up against hair fibres side effects.

Hair transplant

Hair transplants are seen as the ultimate baldness cure. By harvesting thousands of individual hair follicles and implanting them into bald and thinning patches, the procedure can provide amazing results for those looking to tackle hair loss head-on. Literally.

That being said, hair transplants have a lot of side effects to navigate due to its labour-intensive process. Minor effects include: bleeding, swelling, itching and an unnatural result. However, patients could also suffer from infection of the follicles known as folliculitis, bruising around the eyes, and scarring. Not only that, but the process can often be painful and a long term life change which may not suit some hair loss sufferers.

Minoxidil (regaine)

Minoxidil is a hair loss medication that has given some promising results in some users. While it can be an effective treatment for hair loss, it’s not without its side effects. Most minoxidil side effects involve scalp irritation, including burning, stinging and redness. In some cases, it can be absorbed through the skin which can cause major problems. If this happens, users could experience dizziness, irregular heartbeat, chest pain, weight gain and difficulty breathing.

Finasteride (Propecia)

Taken as a pill medication, finasteride claims to slow down hair loss and enhance growth. Oral medications can have a wide range of negative side effects since it actually enters the body, however, finasteride has been known for a few particularly unwanted ones. Among other side effects can include loss of libido, impotence, swelling, dizziness, headaches, insomnia and confusion.

Are nanogen hair fibres safe?

After debunking some of these myths, there are a few real hair fibres side effects to consider before choosing whether to use them or not. And while they can happen, it’s important to remember that any severe symptoms are very rare.

It’s also important to weigh up the hair fibres side effects with those associated with medical hair loss treatments. On the whole, using hair fibres is a lot safer and less risky than any medication or surgery for hair loss. It also provides instant thickness and coverage as opposed to the lengthy medical processes… not to mention a pain-free alternative!

So, it’s “safe” to say that Nanogen hair fibres are safe to use. But, if you are still unsure about the potential hair fibres side effects, make sure you consult your doctor before using it.
