Diseaeases of the Skin.

Contact dermatitis (eczema). prolonged chenical insult to the skin can cause the body to react if the chemicals are harsh abd irritant dermatisis may develop. This condition appears as an inflamed or broken rash.

Impetigo. this is extremely contagious. The bacterial organism which causes it remains within the outer layers of the epidermis. It is found most often on the fasce and manifests itself as inflammation, blisters, pustules and yellow crusts. The client must be referred to a GP for antibiotic treatment. This condition is contra indicated for all treatments. Impetigo can be caused by a cut becoming infected by scrating or the knocking off of scabs. Staphylococci bacteria can then invade the skin and cause infection.

Allergic reaction. a swelling, rash, soreness or open sores may indicate an allergy to a particular product or chemical. The nail may also be white in colour or have white patches. Most nail products have a 48 hour cure time. If the clent has an allergic reation to the product remove as soon as possible.

Tinea Unguium (ringworm of the nails). This condition is rare, but when it occurs it usually affects more than one nail. The infected area will turn yellow or grey in colour. The nails may also become brittle. In severe cases the nail plate may separate from the nail bed. If ringworm has infected the hands the main symptons can be recognised as red lesions occurring in patches or ring, itching can be slight or severe. This condition is highly contagious and contra indicates all treatments.



Bacterial Infection as a nail technician you will see this condition as a yellow of green patch between the nail plate and the product overlay. When applying tips if an air bubble is trapped, moisture inside the bubble will stagnated with a build up of bacteria and change colour. The longer it is left the darker the colour becomes. The colour is a by product of the bacterial infection and not the bacteria itself. Bacteria need warmth, moisture and food to form. Heat is supplied by the blood feeding the nail bed, moisture is in the air trapped and the food is non-living tissue not removed by the technician in the preparation.

Brittle Nails. Brittle nails can be divided into four groups. 01. isolated splits at the free edge which can sometimes extend up the nail plate. 02. multiple splitting across the free edge which resembles the battlements of a castle. 03. lamination of the nail layers at the free edge. 04. nails splitting across the nail plate usually from one corner close to the distal margin. (this type of split can be held together with silk/fibreglass overlay)

Bruised Nails. caused by a clot of blood which forms under the nail after trauma or impact. Sometimes the nail plate needs to be pieced to release the pressure, but this should only be done by a medical practitioner. The client may lose the nail but a new nail will grow underneath.

Hang nail or Agnails. caused by dry cuticles of damaged cuticles. It is just a piece of loose skin hanging off the cuticle, a very common condition, regular use of cuticle oil will help greatly.

White Spots. is simply bruising or trauma to the nail plate. this can be caused by cuticles being pushed back too harshly and damaging the new cells in the lanula. It can also be caused by damage to the nail during your day to day work. It is not due to a lack of calcium.

Bitten Nails. (Onychophagy) nail biting is a habit and very difficult to give up. The condition is obvious to see, but nail extensions often will cure the biter. As a technician it will be up to you to look after the client maybe with a weekly check of the nails, once the habit is broken your client will be very grateful for the care you have shown them.

Onychia. an infection in the nail plate, this can be swollen tissue, redness, soreness or puss. It can be caused by poor technician hygiene. Refer sufferers to their GP.

Verruca Vulgaris (Warts) Warts are small rough lumps on the skin. They are caused by a virus (human papillomavirus) which causes a reaction in the skin. Warts can occur anywhere on the body but occur most commonly on hands and feet. They range in size from 1 mm to over 1 cm. Sometimes only one or two warts develop. Sometimes several occur in the same area of skin. The shape and size of warts vary, and they are sometimes classed by how they look.

Eggshell Nails. the nail plate is very thin. They may be curved on the free edge or sometimes have a dip in the centre of the nail plate. This condition can be heridtary or the client may be on medication. It can also be previous damage form nail extensions done badly due to excessive filing of the nail plate or the client pulling off the acrylic extensions instead of soaking them off in acetone.

Furrows, ridges or corrugations. these can run accross or down the nail plate. Ridges that run down the nail plate are quite normal and can increase with age. Ridges that run across the nail plate could be caused by illness, trauma or poor circulation. Never file the ridges out with a file as this will leave the nails very thin.

Onychorrhexsis. split or brittle nails. The split can be up the nail or across and is usually caused by trauma, excessive filing or overuse of cutile solvents. All nail services can be performed. Where the split is passed the free edge silk wrap or fibreglass may be applied across the split.

Paronychia. this is an infectious inflammatory condition of the tissue surrounding the nails. Quite a common condition that appears as a red and swollen area around the cuticle and sidewall area of the nail plate. Pus formation may be present and the condition can be quite painful. The cause can be a cut to the skin that has become infected. Nail biters and pickers and people that cut their cuticles too often can be prone to this condition. The condition is contagious and the client should be referred to a GP. It is not wise to carry out any service until the condition has cleared up.

Remember even as a professional technician, you are not a doctor or a dermatologist and must NEVER DIAGNOSE A MEDICAL CONDITION.
