As a hair care specialist with years of experience in the industry, I can provide a comprehensive overview of the side effects associated with hair relaxing treatments. Hair relaxing, also known as 'perming' or 'straightening', is a chemical process that alters the structure of the hair to make it straighter. It is a popular method for individuals with naturally curly or coily hair who prefer a straighter, more manageable hairstyle. However, like any chemical treatment, it can come with potential side effects.

Mild Scalp Irritation: The most common side effect, as you mentioned, is mild scalp irritation. This can manifest as redness, itchiness, and a slight burning sensation at the application site. It is generally considered normal to experience some level of irritation during the application of the relaxer. The symptoms are typically short-lived and should subside once the chemicals are thoroughly rinsed from the hair and scalp.

Allergic Reactions: Some individuals may have an allergic reaction to the ingredients in the hair relaxer. This can range from mild to severe and may include symptoms such as swelling, hives, and difficulty breathing. It is crucial to perform a patch test before the full application to identify any potential allergic reactions.

Hair Damage: Over time, frequent use of hair relaxers can lead to hair damage. This can include dryness, brittleness, and breakage. The chemicals in the relaxer weaken the hair's protein structure, making it more susceptible to damage. To minimize this risk, it is essential to follow the recommended usage guidelines and incorporate a deep conditioning treatment into your hair care routine.

Thinning and Hair Loss: In some cases, hair relaxers can contribute to hair thinning and even hair loss. This is particularly true if the relaxer is applied too frequently or if it is not rinsed out properly. The chemicals can cause inflammation and damage to the hair follicles, leading to a reduction in hair density.

Changes in Hair Texture: Another side effect is a change in the natural texture of the hair. Over time, the hair may become more porous and prone to absorbing moisture from the environment, which can lead to frizz and a lack of definition in the hair's natural pattern.

Chemical Odor: After a hair relaxing treatment, there may be a lingering chemical odor. This is due to the strong chemicals used in the process and can take some time to dissipate completely.

Irritation from Residue: If the relaxer is not rinsed out completely, it can leave a residue that continues to irritate the scalp and hair, leading to dryness and potential damage.

To mitigate these side effects, it is important to:

1. Choose a high-quality hair relaxer that is specifically formulated for your hair type.
2. Follow the instructions provided by the manufacturer carefully.
3. Perform a strand test to gauge the strength of the relaxer and the processing time needed.
4. Use a deep conditioning treatment after the relaxer to restore moisture and strength to the hair.
5. Avoid applying the relaxer to the scalp to prevent direct contact and potential irritation.
6. Space out relaxer treatments to give the hair time to recover between sessions.

Understanding and managing these side effects can help ensure that hair relaxing treatments are both effective and safe.
