Hair Care

Frizzy hair?  Use a leave-in conditioner once or twice a week and an intensive conditioning treatment every couple of  weeks. # Ensure your hair is completely dry before you go out, as damp hair frizzes up in all but the driest climates. # Frizz at forehead and ears is due to drying hair from underneath with head flipped forward forces cuticles up. Use a round bristle brush to smooth areas down while drying and and a nozzle to control airflow.

Hair dye allergy. Allergies caused by the molecule pPD (found particularly in dark shades) are a concern. So Wella have introduced ME+, a new dye molecule. It has good colour coverage and vibrancy, with a reduced risk of allergy. The range isWella Koleston Perfect Innocence Colour.

How hair ages
We stop producing melanin as we get older, so colour looks less vibrant and greys appear. Decreased sebum production means hair gets drier. The follicles shrink so hair grows with a smaller diameter, and looks finer as a result. The hair growth cycle shortens so it can be harder to grow hair as you age. Damage from over-use of appliances and frequent colouring (especially bleach) can make hair look dull and more prone to breakage.

Do hair products stop working after a while?
No - hair is an inert substance with no living biological process in the fibre, so there is no way it can get used to an ingredient (unlike antiobiotic resistance). If we switch hair-care products, we do notice a difference  - but that is because the ingredients and their amounts can differ, which means the results won't be the same.

Best Blow Dry: To hold volume and stay frizz-free, hair has to be bone dry. To tell if you've missed damp bits, give hair final blast with cold air, and run fingers through it; areas that aren't dry will feel cooler.

How to wash your hair: sources don't always agree, but here are the most consistently cited tips.

1. Most people do not need to wash their hair every day. If you do, perhaps you are using the wrong products for your hair and scalp type.
2. Apply and massage hair oil (coconut, olive or mustard oil) into your scalp and hair 2 -3 hours before you plan to wash your hair. Shampoos contain harsh ingredients which can strip essential oils from your hair strands and oiling helps to fight this problem.
3. Rinse your hair properly for a minute with lukewarm water before applying shampoo.
4. Only apply shampoo to your scalp. Massage gently in small circles for a minute, then rinse with lukewarm water. (Piling your hair on top and scrubbing it will cause knots.)Work shampoo gently down to the ends of your hair and rinse thoroughly.
5. Forget about lather, rinse and repeat. You only need to shampoo once.
6. If you use a lot of silicone or wax products, try using a clarifying shampoo once or twice a month instead of your normal shampoo.
7. Curly hair is often dry; washing with conditioner alone will freshen hair without drying it out.
8. If you get skin flaking at hairline or temple area, dilute your shampoo by mixing it with water before applying. This will lower the concentration of shampoo applied on the hair and scalp.
9. If you have an itchy scalp after washing your hair, stop applying conditioner to your roots. Start from the mid-lengths and really condition the ends of your hair. Gently comb through and allow it to work for at least 1 minute, the longer the better.
10. Rinse your hair in cold water after making sure you remove all your conditioner as any residue can harm hair and make it look dull.
11. Never brush your hair when it is wet, use a wide comb to gently smooth your hair.
12. Don't rub your hair with a towel; this will cause damage and make hair dull. Gently squeeze out excess moisture and allow hair to air dry.
13. Leaving too much water in your hair after washing will dilute any product you put on and lessen its effect; squeeze out excess water and gently pat hair dry with a towel before applying any conditioner or styling or heat-protecting products.
14. Hair masks are essential if you use heat stylers or colour your hair. Normally this is applied between shampoo and conditioner.
15. Blow dry with hairdryer nozzle point downwards. This flattens the hair cuticle, helping to smooth hair and reduce frizz or flyaways.
16. Use the cold shot on your hairdryer. Hair sets as it cools, so blasting chillier air through your finished style helps keep it in place.
17. Dry shampoo is not just for cleansing; it is also great for reviving flat, limp locks - a few spritzes into the roots can add volume and texture.
