00:36

List the three stages of the hair growth cycle

Summarise your knowledge of the hair structure in no more than three paragraphs.

Cuticle 

• Is made up of transparent overlapping scales 
• Heat/ chemicals will open the cuticles 
• The cuticle scales should ideally be closed from root to tip to give the hair shine and lustre 
• Healthy hair reflects light 
• Damaged cuticle scales will make the hair feel porous and appear dull
• When the hair is in good condition they are water repellent and when in poor condition they will allow more water to be absorbed into the hair making it more porous. 

Cortex 

• This is the section under the cuticle and is where most the action happens.  
• Your natural colour is determined in the cortex and this is where artificial colouring mostly takes place.
• It is this layer that has the bonds which hold your hair in place to determine if your hair is straight, wavy, curly or very curly. 
• Where the hair is temporarily or chemically changed from straight to curly or curly to straight. 
• It is the main part of the hair that gives it's strength and elasticity.  

Medulla  

• The medulla is the least interesting layer. 
• it is the central part of the hair but is not always present. 
•  In a single strand it may fade in and out when analysed under a microscope  or it may be present all the way through in some hair types.
• it tends to appear in more thicker or coarser hair textures.

What causes the cuticle to become damaged?

Describe the difference between Vellus and terminal hair

Vellus Hair 

Vellus hair is the short, thin, and light-coloured hair that occurs during childhood. It can grow up to 2 mm in length. Moreover, it grows in most of the body parts except lips, palm, back of the ear, sole of the foot, etc. The main function of vellus hair is to keep the body warm.

Terminal Hair 

Terminal hair is the thick, coarse hair that grows on your scalp and makes up your eyelashes and eyebrows. After puberty, terminal hair may also grow on your face, armpits, pubic area, chest and belly (abdomen). Terminal hair covers about 30% of your body’s surface in people assigned female at birth. It covers about 90% of your body’s surface in people assigned male at birth.

List all the Non- Infectious Conditions

List all the Infectious Conditions

Non- Infectious Conditions 

Fragilitis crinium- Split Ends

Description: This is commonly known as split ends, where the tip or point of the hair has become dry, roughened and split.

Cause: Harsh physical or chemical treatments.

Treatment: Ideally cutting to remove the split ends. Restructurant conditioning treatments will help to smooth the roughness but will only be temporary. You cannot permanently repair hair that has split.

Trichorrexhis nodosa

Description: This is where hair has become roughened and swollen along the hair shaft and eventually this hair will break off.

Cause: Harsh chemical treatment (e.g. perm rubbers secured too tightly during perming or harsh physical damage caused by elastic bands).

Treatment: Restructurant and penetrating conditioning treatments, but ideally cut damaged hair off.

Monilethrix 

Description: weakened hair due to beaded swellings along the hair shaft

Cause: During development of the hair shaft there is irregular cell production

Treatment: None, although treat gently as the hair is more fragile

Seborrhoea (greasiness)

Description: This is excessive oil produced on the scalp or skin by our oil-producing gland.

Cause: Overactive sebaceous gland, can be stress related.

Treatment: Shampoos for greasy hair and scalp tonics.

Caution: Do not over-stimulate the sebaceous gland by vigorous massage.

Keloids

Description: Overgrown area of rubbery scar tissue larger than the original wound

Cause: Not fully understood but may be a problem with the fibroblasts that produce scar tissue- a poor immune system, hormones and genetics may play apart

Treatment: Steroid injections by GP. In severe cases surgery is used to remove the excess tissue

Damaged cuticle

Description: The cuticle scales are roughened and damaged, creating a dull appearance.

 

Cause: Harsh physical or chemical treatment.

Treatment: Restructurant or penetrating conditioning treatments will help to add strength and shine, but this will only be temporary.

Pityriasis Capitis (Dandruff) 

Description: Small, itchy, dry scales, white or grey in colour.

Cause: Overactive production of epidermal cells; can be caused by stress.

Treatment: Dandruff shampoos (e.g. selenium sulphide or zinc pyrithone) or oil conditioners, tonics or creams applied to the scalp.

Infectious Conditions 

Impetigo

Description: This starts off as small blisters on the skin and develops into large yellow scabs.

Cause: Bacteria entering through broken or cut skin.

Treatment: Medical treatment. This is highly infectious and salon treatment should not be undertaken under any circumstances.

In-Growing Hair

Description: Sore raised areas where the hair follicle is

May become pus-filled

Cause: Close shaving, use of clippers or waxing- hair is removed just below the skin surface, and as it grows it doubles over and grows back on itself

Treatment: If the area becomes filled with pus, antibiotic treatment prescribed by a GP is required-for a very mild case, exfoliation may be enough

Folliculitis- Infectious 

Description: Small yellow pustules with hair in the centre.

Cause: Bacterial infection from scratching or contact with an infected person.

Treatment: Advise medical treatment.

Furunclosis ( Boil or Abscess)

Description: Single, pus-filled red infected lump

Usually found around the neck

Cause: An infected hair follicle

Treatment: Boil is lanced to release the pus by the GP and antibiotic treatment prescribed

Ringworm(Tinea capitis) 

Description: Commonly known as ringworm. Pink patches on the scalp develop into round, grey scaly areas with broken hairs. If left untreated will cause hair loss.

Cause: Fungus spread by direct contact (e.g. touching) or indirectly (e.g. through brushes, combs and towels).

Treatment: This is highly infectious and therefore no salon treatment should be undertaken. Advise medical treatment.

Warts

Description: These are flesh-coloured, raised lumps of skin.

Cause: Virus spread by direct contact (e.g. touching). Warts are only infectious if damaged.

Treatment: Salon services can be undertaken, taking care not to catch them with a brush or comb.

Infestations 

Scabies- Infestation 

Description: Red irritating spots and lines under the skin caused by mites burrowing in the skin.

Cause: Animal parasite known as the itch mite often caught from pets.

Treatment: No salon treatment should be undertaken. Advise medical treatment.

Pediculosis capitis- ( Head lice) 

Description: Commonly known as head lice. Small parasites with six legs live off the scalp by biting and sucking the blood. They re-produce by laying eggs (nits) and cementing them to the hair shaft. They can be very difficult to remove.

Cause: Infestation of lice producing nit eggs.

Treatment: No salon treatment. Advise medical treatment from doctor or pharmacist.
