Sodium Lauryl Sulfate (SLS) is a surfactant that contains around 15-35% in shampoo. That is, a 500ml shampoo contains 150ml of sodium lauryl sulfate.

Will sodium lauryl sulfate cause skin damage?

If you use shampoo and skin care products containing SLS for a long time, it will not be fatal, but it may cause some damage to your skin.

This type of surfactant has a strong degreasing effect and is very irritating to the scalp. Excessive use can cause dry, rough and irritating skin. Long-term use can cause gradual thinning of cell membranes, leading to changes in the transmission of genetic information, which can lead to compromised immune systems.

SLS is a substance with strong cleaning ability. SLS has stronger cleaning ability than SLES, and their cleaning effect is better than SLES, and they are cheap and common in detergents, such as toothpaste, Shampoo, body wash, facial cleanser, laundry detergent, and all kinds of kitchen detergents.

When the concentration is below 0.5%, it will not cause much harm, but when the concentration exceeds 0.5%, they will destroy the oil on the skin, destroy the collagen, destroy the skin's barrier, and cause the skin to become more sensitive , which eventually leads to acne.

Compared with soap, the cleaning effect of the two is the same, but the soap products are fresher and not too dry after washing the face, but it is better to wash it several times.

A shampoo containing sodium lauryl sulfate cleans as well as a soap base, but not as fresh as a soap base, and not as comfortable after use as an amino acid-based product. However, cleaning products such as shampoos with this ingredient can be used as long as they do not exceed the standard.

Does sodium lauryl sulfate cause hair loss?

SLS sodium has decontamination, emulsifying and foaming properties, but it is highly toxic and may cause hair loss. Shampoos containing these surfactants are effective at removing oil from the hair, but when absorbed into the skin, they can cause scalp itching, which can lead to severe hair loss. In addition, these toxic ingredients can also harm the liver.

SLS is widely used in toothpaste, shampoo, shower gel, cleansing oil, detergent, soap, insecticide, etc., and sometimes it can also be used as a food processing agent, such as cake, etc., to foam and emulsify.

Precautions for use of sodium lauryl sulfate:

SLS has an irritating effect on the eyes and has also been reported to cause redness on the face and arms.

Generally speaking, sodium lauryl sulfate should not be in contact with the skin in large quantities. If the skin is accidentally contaminated, it should be washed with water immediately. If this type of surfactant gets into the eyes by mistake, be sure to wash it with water immediately and seek medical attention in time.

When sodium lauryl sulfate enters the nasal cavity, immediately stay away from the contaminated place, take ventilation in time, and if necessary, go to the hospital for oxygen therapy. If children ingest this substance by mistake, they should drink plenty of hot water, induce vomiting, and seek medical attention in time.

SLS has irritating and acne-causing effects on the skin and mucous membranes around the eyes. It is not suitable for long-term use on sensitive skin, dry scalp and hair.
