Benefits of Scalp and Hair Treatment

People who experience itchy and dry scalp may ask for a scalp treatment from any salon
This service provides a wonderful feeling, and it corrects the oil production in the scalp to
encourage healthy hair growth. Scalp treatment can be done for people with oily scalp or those with
dry flaky patches. Having a healthy scalp is necessary to have healthy hair.
Professional hair and scalp treatment are effective to address multiple problems of the scalp
and degrading hair quality including hair loss. This treatment works by tracking the issues from
the roots and revitalizing the follicles. Here are some of the benefits of hair and scalp treatment.
Human scalp hair is a bio-synthesized material that has a complex internal structure. Hair is
a filamentous biomaterial consisting mainly of proteins in par- ticular keratin. The structure of
human hair is well known: the medulla is a loose- ly packed, disordered region near the center of
the hair surrounded by the cortex, which contains the major part of the fiber mass, mainly consisting
of keratin proteins and structural lipids. The cortex is surrounded by the cuticle, a layer of dead,
overlapping cells forming a protective layer around the hair.
A hair and scalp analysis allow us to see the state of your scalp up close. A magnified scope
is used to assess the condition of your skin, the density of your hair and view your hair follicles. The
findings will help to guide in a solution spe- cific for hair problem, such as hair loss.
The following are a few important terminologies in hairdressing:
 hair density- is the number of individual strands per square inch on your scalp.
 keratin- is the type of protein that makes up your hair, a protective protein; the
structural building block of your hair.
 hair thickness- hair is measured on its diameter; it is divided as thin hair in
0.05~0.07mm, normal hair in 008~0.09mm, thick hair called ter- minal hair in
0.1~0.15mm.
 porosity- the ability of the hair to absorb moisture
 elasticity- the strength of the hair and its ability to return to its original state without
breaking
Diseases and Disorders of Scalp and Hair

1. Seborrheic Dermatitis. Dandruff is a mild form of seborrheic dermatitis. In more
severe cases, a reddening of the scalp and a lot of oil happen. There may also see reddish, greasy crusty
scales between your eyebrows, and around your nose and ears.
2. Cradle Cap. This form of seborrheic dermatitis affects infants, typically in the first 6 months. It
causes greasy, yellowish scales or crusts on the scalp. Although it may frighten parents, cradle cap is not
a sign of a more serious infection, and it will usually clear up by the baby's first birthday.

3. Head Lice. Lice are an unpleasant but all-too-common part of childhood. Lice are wingless insects
about the size of a sesame seed. They feed on blood, and the females lay their eggs on the hair close to
the scalp.
4. Ringworm. It's an infection that leaves round, scaly, red rashes and patches of hair loss on the
scalp. Ringworm is most common in children between the ages of 3 and 7, but it can affect adults,
too. It’s spread through close contact or by sharing hats, clothing, towels, and combs. In rare
cases, it's possible to catch ringworm from a dog or cat.
5. Folliculitis. Folliculitis is an inflammation or infection of the hair follicle, the sac that contains the
root of the hair. It's usually caused by bacteria (usually staphylo- coccus) that find their way into the hair
follicles from a nearby infection. The follicles also can be irritated from shaving, makeup, or
clothing. Some people get folliculitis after taking a dip in a hot tub.
6. Psoriasis. This skin condition can show up anywhere, but often happens on the scalp. It causes the
body to make too many new skin cells. This buildup can form thick, crusted scales that can feel itchy or
sore.
7. Lichen Planus. Lichen planus affects the skin or mouth. Doctors believe lichen planus is an
autoimmune disease, which means your immune system attacks your own body by mistake. People who
have lichen planus develop flat-topped, purple, or reddish bumps on their skin. And they usually itch.
Other symptoms include red- ness, irritation, and (sometimes permanent) hair loss.
Safety Precautions and Sanitation
Health and safety must be a priority in your beauty salon. It’s vital to pro- tect
your staff and clients, operate within the law and be insured against poten- tially expensive
legal action should something go wrong.
A. Carry out a risk assessment. Make a list of anything that could cause injury or harm
in your work place, and set out the steps you have taken.
• Contact with water, detergents or massage oil that irritate the skin.
• An allergic response to chemicals; this can take a while to develop.
B. Musculoskeletal problems. Staff may experience strains, sprains and general pain due to
doing physically repetitive work that involves a lot of standing and bending.
C. Create a health and safety policy. Health safety protocols should always be imposed.
An allergy alert testing must be carried out allergy alert tests at least 48 hours before applying
hair colour or eyebrow/eyelash tints.
D. Treatments and health safety. Always follow manufacturers’ instructions and
make sure the client is old enough to have the treatment or therapy and does not have any
medical condition which would put them at risk.
Dealing with hazardous products

 Ensure that you are knowledgeable enough on how to use and dispose them safely.
 Always store hazardous substances in their original containers, away from direct
sunlight and preferably in a locked cupboard.
 Make sure you know which substances should not be poured down the sink.
Keeping the Workplace and Equipment Safe
• The workplace should be adequately ventilated.
• Gas and electricity appliances should be regularly checked.
• Measures should be taken to avoid slips, trips and falls.
• Guard against legionella by checking your water on a regular basis. Spe-
cialist checks are required for spa operators.
• There must have a smoke detectors, fire extinguishers, a clear evacuation
plan.
