Which is better, washing your hair once or twice?

Regarding the matter of washing hair, the speed faction believes that "going through it once, saving water and worry"; The second brush faction shouted, 'You must wash twice to clean your scalp.'.

So, which one is better? How can I avoid falling into misconceptions when washing? Today, an article provides an answer!

Which is better, washing your hair once or twice?

The reason for being speed oriented sounds tempting: ending the battle in 5 minutes, getting it done in one go, saving time and effort, suitable for early eight people, overtime workers, or lazy people. Supporters of the second brush faction are often oil headed celebrities, fitness enthusiasts, or hairstylists. The first wash (pre cleaning) is to dissolve oil and open pores; The second washing (main cleaning) is more rich in foam, which can completely remove dirt.

Which frequency is better for washing hair?

Oily scalp (daily oiliness, flattened hairstyle): It is recommended to wash twice, but with a 5-minute interval. The first time, use a small amount of shampoo to quickly remove oil, and the second time, focus on massaging the scalp. Neutral/dry scalp (2-3 days of oily and dry hair): Wash once is enough, choose a mild amino acid shampoo, and avoid carrying too much oil.

Caution, do not over clean! The scalp itself is weakly acidic and has its own ecological balance. Frequent use of strong alkaline shampoo can damage the acidic protective film, leading to dryness, dandruff, and even hair loss.

Have you ever encountered these hair washing misconceptions?

Shampoo must be washed thoroughly, otherwise it will cause hair loss

Truth: A small amount of shampoo residue will not cause hair loss, but long-term residue may clog hair follicles. Rinse until there is no slippery feeling.

Applying hair conditioner to the scalp can cause baldness

Truth: Hair conditioner mainly acts on the ends of the hair. Applying it to the scalp may cause greasiness, but it will not directly lead to hair loss unless you are allergic to the ingredients.

Natural air drying is better than blowing dry

Truth: When wet hair, the hair scales open and are easily damaged by friction. The correct approach is to use a towel to absorb moisture and blow it to a low temperature of 8 minutes to dry.

How to wash hair scientifically?  

The appropriate amount of shampoo is sufficient for short to medium hair: 1 yuan coin sized (about 5ml) per session. Long hair and waist: 2 coins the size of 1 yuan each time (approximately 10ml). Key points: first rub out foam on the palm of your hand and then put it on the top to avoid the local concentration being too high due to direct application.

The water temperature control of 38 ℃ is too hot for the golden line (>40 ℃): it stimulates hair follicles and aggravates dandruff. Too cold (<30 ℃): Decreased oil removal ability, washed away a "loneliness". Tip: Try the water temperature with your hands and feel it is "warm but not too hot".

There are two special scenarios for washing hair that require attention to detail

after workout

Because the scalp will sweat and produce oil after exercising, some fitness enthusiasts may wash their hair once more than the average person, but they also worry about whether washing their hair twice a day is too damaging to their scalp?

Solution: temporarily absorb oil with dry hair spray, or rinse hair roots with water only, and then wash hair normally after returning home.

After dyeing and ironing

Hair dye and perm solution may damage the scalp barrier, so it is recommended to avoid washing hair for 3 days after dyeing and perming. This not only allows time for scalp maintenance, but also helps to fix the color. Afterwards, you can use color protection shampoo, with a water temperature not exceeding 35 ℃, and wash once.
