Whatever may be the occasion, a new hair cut or hair color is the way to rock it up. Be it, men or women, both genders are equal fans of good hair color and so our cosmetic industry is continuously busy in developing better options to suit every individual. Since the past few years, we have seen a revolution in hair dyes, so there exists a lot of confusion among which to get hands-on. Let’s explore the two primary hair color varieties, the demi-permanent, and the classic permanent hair color.
Demi-permanent Hair Color
It is an alkaline-based, ammonia-free color that offers an understated approach. Being Ammonia free, it only deposits color onto the hair by slightly penetrating hair shaft without raising the cuticle, which makes the color stay temporarily on strands. A demi-permanent dye lasts typically up to 28 washes, losings its strength every time. It doesn’t need any developer but could contain some or no amount of peroxide depending upon the brand works best for anyone who wants to keep experimenting with new colors frequently. It typically washes away in 25 shampoos allowing to change according to moods. It could be termed similarly to a lip stain. The fading process could be speeded up by continuously using a clarifying shampoo.
Using this exquisite liquid formula, you could add luster to dull looking hair for a refreshed look.
It is particularly loved by people who wish to add a darker color to hair. This product cannot lighten hair as it uses only a small amount of peroxide, which is insufficient.
Women with textured hair feel free to use the demi-permanent color because it doesn’t penetrate the hair follicle and change or damage your natural curls. For people with less than 25% gray, this dye is most appropriate because demi-permanent hair color stays only on the hair follicle surface, giving your gray hair a translucent and highlighted appearance. It refers to reduces the appearance of regrowing roots.
Permanent Hair Color
Just corresponding to its literal meaning Permanent hair color means clearly that IT IS PERMANENT. As opposed to the demi-permanent, it’s the classic long haul which provides a rich, lush, and ultra-long-lasting color to all kind of hair types and colors.Permanent hair color can lighten virgin hair (i.e., hair that has never been colored) up to two shades without the need for additional steps like bleach.
When Permanent hair color is applied, it interrelates with the natural coloring of your hair. Its tiny transparent molecules sink into the hair cuticle with the help of ammonia. Then combine with hydrogen peroxide and generate a chemical reaction termed as oxidation, which locks in the color in the hair fiber.

Permanent hair color lasts for months, depending on your hair growth rate; only touch-ups to roots are required once a month typically. Also, to completely cover grey hair, these permanent hair colors are idle.
Permanent dyes seem to be more damaging to your hair because of the strong chemicals used don’t like the color, or the color you selected didn’t turn out as it should have been. They have also been known to cause allergic reactions causing itching, redness, skin irritation, or swelling on the scalp or at the face and neck.
Even cancers have been associated, but these accusations have been proved yet. Still, these claims cause a great deal of discomfort among customers.
To be on your safe side, try to avoid permanent dyes, and people with sensitive skin conditions like eczema and psoriasis must not use these dyes at all.
On the other hand, some people argue in favor of permanent hair colors that as demi-permanent dyes don’t last long, so people who want big-time colored hair would need to dye hair repeatedly, exposing hair to chemicals again and again. While permanent dyes last a lot longer, leading to low chemical exposure leading to more damage.
