If you wash the dye off too soon, you will just waste the chemical. On the other hand, if you leave hair dye too long, it may affect your hair color or texture. In this article, we explain factors to consider and the ideal duration for hair dyes. 

Factors to consider on how long do you leave hair dye in 

The recommended duration for leaving hair dye depends on the factors listed below: 

Normal color of your hair

Before buying chemicals and accessories for styling your hair, you should consider its authentic color. As your hair grows, its natural hue may interfere with that of the dye. It is advisable to check the dye’s packaging material for the resulting coloration after its application. Moreover, select the one that gels well with your hair’s normal tint. 

Amount of Gray Hair 

If you have a significant amount of gray hair due to aging or genetics, you may leave hair dye on for extended periods. This step is necessary to thoroughly cover the strands. Moreover, you will need an enduring dye to paint the hair perfectly.  

Your Hair’s Present Tint 

What is your hair color at the moment? This knowledge will affect the choice of hair dye to use. For instance, if your current hair shade is darkish, you cannot apply a lighter tint immediately. Rather, you will remove the old dye and restore your hair to its normal color. Afterward, you may apply the new dye and may leave hair dye for a longer duration. 

Hair Sponginess 

Sponginess refers to the capacity of your hair to soak up water easily. Hair with high sponginess takes up the dye without stress. You may end up spending less time. However, if your hair has low sponginess, the duration will likely increase. 

Your Hair Thickness 

All hairstyles for girls have one of these three thickness ranges – fine, moderate, and dense. Fine hair often possesses tinier strands. Thus, you need minimal chemicals and time to change its coloration. Moderate hair is the most common and it requires about 45 minutes for thorough dyeing. People with dense hair need more chemicals and must leave the hair dye on for a longer duration. 

How long to leave semi permanent hair dye in 

Several hairstyles often require dyes to enhance their texture and appearance. The term “semi permanent” refers to dyes that lack stronger constituents such as ammonia and peroxide. As a result, you can wash them off with minimal issues. Also, they do not change the shade of your hair completely. 

Quite often, semi permanent dyes only coat the outer portion of your hair. This way, your hair follicles remain intact. Moreover, if you leave the hair dye on for an extended period, consider adding salt to the water. It softens the scalp and hair strands for easier removal.

Moreover, be careful when applying the blue dye because of scalp damage. If your hair is too dry, the damage may be pronounced. Try moisturizing your hair for easier application.
