GSalons is based in Shoreditch, London. We offer high quality professional hair services specialising in Keratin Hair Colour services and Treatment.

All treatments at G Salons are carried out by Keratin specialists. Consultations are done with every client where we give advice on how to care for your hair at home and how get the best out of your keratin hair treatment – which is checked before you leave. Guaranteed quality.

Keratin Treatments can be used on all hair types including chemically treated hair (coloured, permed, relaxed, highlighted or bleached) and is especially beneficial for damaged and porous hair.

It is recommended that hair colour be applied on the same day, prior to the Keratin Treatment. The treatment will lock in hair colour, making it appear more vibrant and increasing its longevity.

The high quality Keratin treatments used in the salon infuse Keratin deep into the hair cuticle, leaving the hair smooth, shiny and luxurious. Results typically last 3-4 months depending on hair type.
To maximise treatment results we recommend using the post-treatment maintenance products which contain Keratin, are free of salt and sulphates and are specially formulated to prolong the effects of the Keratin treatment.

Hair Porosity

Porosity is the measure of the hair’s ability to absorb moisture. This is determined by the condition of the hair’s cuticle layer (the overlapping scales of the hair shaft), and is rated as low, normal, and high. In normal, healthy hair, the cuticle is compact and inhibits the penetration of the hair shaft by moisture – both moisture going in, and moisture coming out. When the cuticle is overly compact and prevents the penetration of the hair by moisture it has low porosity.

Hair with high porosity is hair whose cuticle layer is open and the hair too-readily absorbs moisture. Overly-porous hair also releases moisture easily and becomes dry and is easily damaged.

Extreme caution must be used when performing chemical services on overly porous hair to prevent damage. Hair colour will take much more quickly and strongly in overly porous hair (and semi-permanent and demi-permanent hair colours will fade much more quickly). Perms and straighteners will process much faster in high-porosity hair as well.
To determine the porosity of your hair, simply feel it – both when wet and when dry. If the hair feels straw-like and rough when dry, or if it feels gummy or slightly rubbery when wet, then you probably have a problem with overly porous hair.

Porosity IS a form of damage to the hair. It can be caused by many reasons and just because you are natural, it doesn’t mean you can escape it!! Here are a few causes of porosity:

  1. Shampooing, Towel Drying and Combing
    These three are some of the most common reasons for cuticle damage. They can cause any of the damage seen in the figures above and it is mostly attributed to one main factor, mechanical damage. Mechanical damage happens when scrubbing the hair with shampoo, rubbing the wet hair with a towel and combing hair to remove tangles. The more aggressive you are at any of these activities, the more susceptible your hair will be to damage.


  1. Long Hair
    The longer your hair has been on your head, the more likely it is to have a damaged cuticle simply because it will have been exposed tonumber 1 multiple times.


  1. Light
    UV light/sunlight has also been seen to damage the cuticle with one study showing that damage starts after 200 hours of exposure which is a fairly long time.


  1. Chemical Treatment (Relaxing and Bleaching)
    Both these processes are an open invitation to porosity (bigger and better than ever). Cuticle lifting, cracks, holes are common with the added punch of entire sections of cuticle missing.


  1. Others 
    Environmental conditions such as dirt, wind, humidity as well as thermal treatment (heat setting, blow drying, flat ironing).
