RelaxeR StRand teSt
Just before performing a relaxer
service, or on the day you
perform the patch test, take
a few strategic test strands to
ensure the relaxer is the right
strength, the hair remains in
fairly good condition, and the
hair relaxes as expected. This
will save you many unwanted
surprises. (Figures 15-9
and 15-10).
Select a strand at the back, and one on each side of the head. Separate each strand from the rest of the hair, apply
the relaxer as directed, and monitor the relaxation process. Midway through the recommended processing time,
lift each test strand, gently stretch and release the strand, and observe the curl reversion. You can also do this
by using the back of a comb to remove the relaxer and then observe the curl reversion. Is the hair halfway there?
Almost there? After this point, check the test strands at five-minute intervals until the process is complete.
Relaxer Safety Tips
Refer to the following for helpful safety tips for before, during, and after the relaxer service.
Before Relaxer Service
• Use only plastic or glass bowls and plastic clips when relaxing hair. Do not use metal.
• Apply relaxer to hair that has not been shampooed for one week.
• Apply if the client has fragile hair and avoids swimming in the ocean, soaking in chlorinated hot tubs, and
participating in other activities not compatible with fragile hair.
• Decline a relaxer service if the hair has been treated with henna, which interferes with all texture services.
• Decline a relaxer service if the hair has been treated with metallic dyes, which are chemically incompatible
with relaxers.
• Establish a treatment program to restore the hair’s strength and elasticity before scheduling a relaxer service.
Caution!
Sodium hydroxide and thio
relaxers are chemically
incompatible and can
cause severe damage—
even hair loss—when mixed
or overlaid on the hair.
• Neverusesodium
hydroxide relaxers on hair
previously relaxed with a
thio relaxer.
• Neverusethio relaxers
on hair previously
relaxed with a
hydroxiderelaxer.

During Relaxer Application
• Precisely apply base cream without overlapping on hair that
will be relaxed.
• Wear protective gloves when performing every relaxer service.
• Avoid using two different relaxer types. Do not apply a hydroxide
relaxer to hair that has been relaxed with a thio relaxer and
viceversa.
• Apply a relaxer formulation appropriate for the client’s hair
texture and condition.
• Apply to the midshafts, then the scalp area, then the hairline, and

• Use your gloved fingers to smooth the relaxer through the hair.

• Separate the hair in sections using your fingers, the tail of a tail
comb, or an applicator brush without touching the scalp.
