Cruelty Free - Cruelty Free - Animal Testing

Are your products tested on animals?

The total ban on testing and marketing cosmetic ingredients and products tested on animals came into force all over the European Union on 11 March 2013 with the new cosmetic regulations No. 1223/2009.  After a long process of gradual bans that lasted almost 20 years, the official NO to all tests on animals in the cosmetic sector has finally come into being.

Bios Line does not and never did carry out tests on animals (or on raw materials or finished products – Law 713/86 and subsequent modifications).To guarantee quality, effectiveness and product safety for customers, Bios Line uses methods other than tests on animals, carrying out in vitro or dermatological tests in co-operation with the best Italian universities.This commitment is expressed also through the concrete support of the research for methods that do not include animals in safety and toxicity tests promoted by the Fund for the Replacement of Animals in Medical Experiments (FRAME – www.frame.org.uk).

CRUELTY FREE - Cruelty Free - Animal Testing

(Italiano) Perché non trovo nei vostri astucci o nei materiali di comunicazione nessun simbolo di "non testato sugli animali"?

(Italiano) Non riportiamo comunicazioni al riguardo perché, come afferma una sentenza del Giurì dell’Autodisciplina Pubblicitaria,  le diciture “stop ai test su animali garantito da LAV” e “non testato su animali” sono sicuramente in contrasto con il Codice (Regolamento UE n. 355 del 10.07.2013), in quanto possono lasciare intendere al consumatore che altri prodotti cosmetici sperimentano sugli animali, quando invece ciò è vietato per legge. Anche il riferimento a LAV è secondo il Giurì irrilevante, in quanto il messaggio viene decodificato non come adesione di tipo ideologico alla proposta generale di bandire i test sugli animali anche al di fuori del settore cosmetico, ma come pregio specifico del prodotto.

Allergy to Nickel - Nickel Tested

Just this week I found out I have a very strong allergy to nickel. Could you please tell me whether your products contain it?

As regards the absence of nickel in cosmetic products, it is only fair to clarify that it is virtually impossible to completely avoid the presence of this mineral, as it is contained in trace amounts in water and in the steel mixers where the products are prepared. Precisely for this reason, BiosLine has chosen to promote its cosmetic products as “Nickel Tested”.
This means that every production lot of BiosLine Nickel Tested cosmetic products undergoes analysis for nickel.


I have already used hair dyes without any allergic reaction, can I use BioKap Nutricolor?

Not without performing the patch test. Each dye is different and because there may be allergies to even the most innocuous products such as certain foods (nuts, tomatoes etc.), it is essential to perform the patch test 48 hours before each application. This must be done, even if you have already used a colouring product from this or another brand, because individual sensitivity to the dyes may change over time.


How do you perform the patch test?

Mix a small amount of BioKap Nutricolor Colouring Cream with an equal amount of Nutrifix Colour Developer lotion. As a container you can use a lid, a paper cup or a coffee cup.

Using a cotton bud, apply a small amount of the product behind the ear or in the crook of the elbow, enough to cover an area equal in size to about 1 cm square.

Repeat this two or three times, letting it dry in between. Close the colouring cream tube and the Nutrifix lotion bottle carefully, then wait 48 hours without washing, covering or touching the area.

If itching, redness or other skin abnormalities occur during this period, do not use the product and consult a dermatologist before using any other colouring product.

The patch test is a sensible precaution that can reduce, but not eliminate, the risk of an allergic reaction, even in the event of a negative result. If, after this period, no itching, redness or swelling is evident, apply the BioKap Nutricolor Dye product.


Can I colour my hair during pregnancy and while I am breastfeeding?

Regarding the use of our hair dyes during pregnancy, we recommend following the advice of your gynaecologist.

In fact, although the ingredients are selected to ensure high skin tolerance, we must consider that during pregnancy, skin is more sensitive, therefore there is an increased risk of sensitization or allergy, even in women who have never experienced this type of problem.

For this reason, we do not recommend using any hair dye in the first three months of pregnancy and, for the other months, we suggest you consult your gynaecologist:some recommend the use of natural dyes from the 4th month onwards, while others only after pregnancy and breastfeeding.

DYES AND WARNINGS - Biokap Nutricolor Dyes

Are there situations where it is not recommended to use hair colouring products?

Hair colouring products must not be used if the user:

– has had a previous reaction to dyes;
– has a sensitive, irritated or damaged scalp or rashes on the face;
– has had a reaction to a temporary black henna tattoo.

In addition, these products are not intended to be used on persons under the age of 16.

DYES AND EYES - Biokap Nutricolor Dyes

What should I do if I get the product in my eyes?

In this case, rinse immediately for a prolonged period with plenty of water.

IF YOUR SKIN GETS STAINED - Biokap Nutricolor Dyes

How can I get rid of stains on my skin?

The dye will disappear after a few washes. To prevent stains, however, you can apply the protective cream supplied in the pack, or another oily cream, around the edge of the scalp.

DYES AND DURATION - Biokap Nutricolor Dyes

After how long is it advisable to repeat the application of the dye?

It is usually best to wait 5-6 weeks before repeating the application, but times may vary depending on the speed of hair growth.


Can I apply the dye after using henna or highlights?

It is first necessary to perform the patch test 48 hours before each application. The dye can be applied, but we cannot guarantee the colour result, because the previous treatment can alter the final colour of the first application compared to the desired one. Subsequent applications, one month apart, can help obtain the desired colour.We nevertheless recommend choosing shades that do not have red hues and testing a strand behind your neck to see the colouring result. We do not recommend the application of  BioKap Nutricolor Delicato + Hair Dye.


I would like to know if your anti-cellulite products can also be used during pregnancy.

Due to the particular level of certain hormones during pregnancy, a woman’s skin becomes more sensitive and likely to show sensitization reactions.
As a consequence, products such as anti-cellulite* ones, which stimulate the skin, could cause redness and itching.
I would suggest Cell-Plus Crema Rassodante with FRV be applied on the stomach, hips and bust to prevent the appearance of stretch marks.
*skin appearance
Furthermore, bear in mind that it is quite normal that, during pregnancy and breastfeeding, fluid retention in the tissues increases due to hormones. It would actually be counterproductive to undergo treatment of any kind to reduce the volume of fluid in the tissues: women need to accumulate fluid for the continuous replacement of amniotic fluid and, later on, to produce milk.

DYED HAIR - Biokap Nutricolor Dyes

Can I use Biokap Nutricolor despite the fact that my hair are already dyed ?

Yes, it is possible to apply BioKap Nutricolor on already dyed hair. If you need to just touch up your roots, choose a colour that is similar to the one you already have.  If instead you want to change your present look , choose a darker colour than the one you already have.  If you have a high percentage of white hair,  apply a colour that is one tone darker than your hair in order to get a perfect coverage. Like all permanent hair dyes, we recommend to wait at least 4/5 weeks between one application and the next one.


Can I use your anti-cellulite products while breastfeeding?

In this particular period, because of hormone levels that are established during breastfeeding, cellulite becomes more evident and it is very difficult to lose weight: prolactin, in fact, leads to considerable fluid retention, a prerequisite for the production of milk. Generally, experts advise against starting a low-calorie diet and/or exercise program aimed at weight loss while a woman is breast feeding, because milk production could be affected.
And also as regards cosmetic treatment and food supplements, for the same reasons mentioned above, I advise you to defer their use until the end of breastfeeding: anti-cellulite/slimming products always result in drainage of the fluids present in the tissues, which is counterproductive for milk production.

(Italiano) ALLERGIA AL NICKEL - Nickel Tested

(Italiano) Sono allergica al Nickel, posso utilizzare le vostre tinte?

(Italiano) Tutti i prodotti della linea BioKap Nutricolor sono “Nickel Tested” (vedere la domanda sopra) come riportato su ciascuna confezione. Significa che il prodotto finito di ciascun lotto di produzione viene sottoposto ad analisi per il nickel.
In ogni caso è necessario eseguire una prova preliminare di sensibilità, 48 ore prima di utilizzare il prodotto.

CUSTOMISED COLOURS - Biokap Nutricolor Dyes

Can I mix different shades together?

If you do not find among  Nutricolor e Nutricolor Delicato the color that better suits you, it is possible to mix the differnt colos among them.
Please note that  the new 4 BioKap Nutricolor Delicato + colors, on the other hand, MUST NOT BE mixed neither among them nor with any other color.

We remind you that any residual of hair dye that has been already mixed and is ready for use cannot be stored and used later. It is nevertheless essential to perform the patch test 48 hours before each application. This must be done, even if you have already used a colouring product from this or another brand, because individual sensitivity to the dyes may change over time. A preliminary test should be carried out to check the final colour. Proceed by mixing varying amounts, depending on the result to be obtained, from the chosen colour tubes in the same bottle of Nutrifix Colour Developer.

DEVELOPMENT TIMES - Biokap Nutricolor Dyes

How long should the dye be left on to develop?

For correct application, the development time is a total of 35 minutes. It is recommended to apply the dye on any regrowth, leaving it on for approximately 20 minutes, and then distribute it along the length of the hair, leaving it on for another 15 minutes.

DYES: LIGHTENING CREAM - Biokap Nutricolor Dyes

How should the Lightening Cream be used?

The Lightening Cream should be applied in the same way as the BioKap Nutricolor Dye, with some small changes:

– to lighten hair by 1-2 shades: apply over the entire length of the hair, leaving it on for 30/40 minutes;
– for highlights: apply to small sections using the special applicator, wrap in aluminium foil and leave on for 30 minutes.

Some guidelines: if your natural colour is

– dark blonde, your hair will turn light blonde
– brown, your hair will turn light brown
– red, be careful as the colour could become orangey
– dark brown/black, application is not recommended.


I don’t like how the colour has turned out. How can I get my natural colour back?

If the chosen colour is one or two shades darker than your natural colour, you can lighten your hair using BioKap Nutricolor Delicate Lightening Cream. If the chosen colour is one or two shades darker, you can apply a darker shade of dye.Before doing any of this, it is advisable to wait 4-5 weeks from the first dye. If the chosen colour is much lighter or much darker, it is advisable to contact your hairdresser.
